You've handled hard things your whole life. So why does everything suddenly feel like too much? Here's what many women still don't know about perimenopause and your nervous system.

You wake up at 3am with your heart racing. There's no reason. You were just… asleep, and then suddenly you weren't, and now your mind is running a list of everything that could go wrong and you can't make it stop.
Or maybe it's not the middle of the night for you. Maybe it's the moment you get in the car and your chest tightens for no reason you can name. Or the way small things now send you over the edge like the wrong tone in a text, a meeting that ran long, a question from your partner that wouldn't have bothered you two years ago.
You've always been the one who handles things. So this feeling, this undercurrent of dread that won't fully go away, doesn't make sense to you. And the worst part is not even the anxiety, but the thought underneath it.
Is something wrong with me? Am I losing it? Why can't I pull myself together anymore?"
You're not losing it. But something is happening and it's not a breakdown, and it's not permanent.
It's perimenopause.
What perimenopause anxiety actually feels like
Here's the thing about perimenopause anxiety that nobody really prepares you for: it doesn't feel like the anxiety you've maybe had before. It feels different. Bigger. Faster. More physical.
The anxiety you might have dealt with in your thirties was manageable. You had tools for it. You could talk yourself down. This feels harder to reach. More like something is happening to your body than something your mind is generating.
Women I work with describe it like this:
A sense of doom that arrives without warning and doesn't make logical sense
Heart racing, chest tight — and then nothing's actually wrong
The feeling of being constantly on edge, like something bad is about to happen
Waking between 2am and 4am with racing thoughts that won't quit
Irritability that comes out of nowhere, bigger than the situation warrants
Feeling overwhelmed by things that used to feel manageable
A kind of internal hum — background anxiety that's always there now
Social situations or confrontations that feel way harder than they used to
Difficulty making decisions, even small ones
The feeling that you're running on empty no matter how much you sleep
Does any of that sound familiar?
If it does, you are not falling apart. Your nervous system is responding to a massive hormonal shift, and that shift is affecting your brain chemistry in ways that make anxiety more intense, more physical, and harder to manage with the strategies that used to work.
Why perimenopause makes anxiety worse — what's actually happening
Let's talk about what's going on in your body, because understanding this changes everything. Estrogen deeply involved in regulating your mood, your sleep, your stress response, and your nervous system. When estrogen starts to fluctuate in perimenopause, which can begin in your late thirties or forties, long before your periods actually stop, your brain's ability to regulate itself changes.
Specifically: estrogen helps regulate serotonin and GABA, two of the key neurotransmitters involved in anxiety and calm. When estrogen drops, those systems get disrupted. Your nervous system becomes more reactive. Your stress response — the fight-or-flight system — gets triggered more easily and calms down more slowly.
WHAT THIS MEANS FOR YOU
The anxiety you're feeling is not coming from a flaw in your coping. It's coming from a physiological shift that affects the parts of your brain responsible for staying calm. You didn't cause this. Your nervous system is working harder than it ever has, and it needs support, not criticism.
And here's another layer: if you've spent your life as a high-functioning woman managing everything, holding things together, staying strong for everyone around you, your nervous system has probably been running on empty for a long time already.
Perimenopause doesn't create the anxiety from nothing. It turns up the volume on a nervous system that was already working overtime. What you might have been managing (just barely, maybe) for years suddenly becomes unmanageable.
When anxiety shows up — but you don't look anxious
One of the loneliest parts of perimenopause anxiety is that from the outside, you probably look completely fine.
You're still going to work. You're still showing up for your family. You're still the person people call when things go wrong. Nobody would guess that inside, you're white-knuckling through most of it.
High-functioning anxiety in midlife looks like:
Staying constantly busy because stillness feels dangerous
Preparing obsessively for worst-case scenarios
Saying yes when you desperately want to say no
Struggling to delegate because you don't trust anyone else to do it right
Using productivity to outrun the feeling that something is wrong
Collapsing internally while presenting as completely capable externally
If this is you, I want to say something that might feel uncomfortable: the way you've been coping is actually making the anxiety worse. Because the coping strategies that got you this far like pushing through, staying busy, keeping it going, are nervous system strategies. And they work, until they don't. And perimenopause is often the moment they stop working.
You have spent years managing your anxiety by being excellent. Perimenopause is asking you to try something different.
What doesn't help (even though it should)
By the time most women reach me, they've already tried a lot of things. And they're frustrated because the things that should help, and used to help, are not working the way they expect.
And therapy, even good therapy, an hit a ceiling if it stays at the level of insight and doesn't address what's happening in your nervous system. You can understand exactly why you're anxious and still be unable to stop the physical response.
This is one of the things I see most often with the women I work with in perimenopause. They're smart. They've done therapy before. They understand their patterns. And they're still lying awake at night with high anxiety, because understanding is not enough. The nervous system needs something different.
What actually helps perimenopause anxiety
Healing perimenopause anxiety means working at the level where it's actually happening — your nervous system, your body, the parts of you that react before your thinking mind even has a chance to catch up.
This is where somatic therapy becomes so important. Somatic work helps your body learn to feel safe again through direct experience. It interrupts the patterns of activation that keep you stuck in fight-or-flight and teaches your nervous system a new way of being.
It also means looking honestly at the life that's surrounding the anxiety. What are you still carrying that is not yours to carry? Where are the places you're saying yes when your whole body is saying no? What does the anxiety actually need you to change?
And it means making space for the grief. Because perimenopause often brings grief with it — for the body that felt reliable, for who you used to be, or the life you thought you'd have by now. Anxiety can be unexpressed grief. When grief finally gets witnessed and processed, anxiety often quiets.
WHAT I WORK ON WITH CLIENTS
In my work with women in perimenopause, we focus on nervous system regulation, learning to recognize when you're activated and what to do about it at the body level. We process the old material that's surfacing. We work on what it means to be a woman in midlife who is changing. And we do it in a way that's actually paced for your life — not one hour a week that you have to wait seven days to revisit.

Why weekly therapy often is not enough during perimenopause
If you've done weekly therapy and feel like you've hit a ceiling, you're not imagining it.
One hour a week can be meaningful. But in perimenopause, when your nervous system is shifting rapidly and there's so much material surfacing at once, the pace of weekly therapy often can't keep up with what's happening in your body and your life.
This is why I offer therapy intensives — extended sessions of several hours, or a full day, where we can go deep without the clock ending the work just as something real begins to open.
Intensives allow your nervous system to actually land somewhere new instead of activating, getting close to something, and then having to stop and wait a week to come back. They create sustained, spacious attention that real nervous system change actually requires.
If you're in perimenopause, this can make an enormous difference.

This is not who you are. This is what you're moving through.
You're not broken or weak.
You're in the middle of one of the most significant transitions of your life, and her nervous system is telling you that something needs to change.
Anxiety in perimenopause is not a life sentence. It's a signal. And when you learn to work with it, it can become the beginning of life that's finally yours. Not the one you've been holding together for everyone else.
You don't have to figure this out alone.
If you're in perimenopause and the anxiety has become too much to keep managing on your own, I'd love to talk. I work virtually with women throughout Illinois — no commute, no waiting room, just real support.

Frequently asked questions
Can perimenopause really cause anxiety even if I've never had anxiety before?
Yes — you don't have to have a history of anxiety to develop it in perimenopause. Estrogen plays a significant role in regulating your mood and nervous system, and as levels begin to fluctuate, many women experience anxiety for the very first time. If this is new for you, that's actually important information: it's a strong sign that hormonal shifts are involved, and that the right support can make a real difference.
How do I know if what I'm experiencing is perimenopause anxiety or just regular stress?
A few things can help you tell them apart. Perimenopause anxiety often feels more physical like heart racing, chest tight, a sense of doom that arrives without a clear trigger. It can also feel disproportionate: bigger than the situation warrants, and harder to talk yourself down from. If it's happening alongside other changes — irregular periods, sleep disruption, hot flashes, changes in your cycle — that context matters. But honestly, you don't have to have a definitive answer before you seek support. If the anxiety is affecting your life, that's enough reason.
What age does perimenopause anxiety usually start?
Earlier than most people expect. Perimenopause can begin in your late thirties but most commonly in your early to mid-forties, and the mood and anxiety changes often appear before the more recognizable physical symptoms like hot flashes or irregular periods. Many women I work with had no idea their anxiety was connected to perimenopause because they were still having regular periods and assumed they were years away from any hormonal shift.
Will the anxiety get better on its own when I get through perimenopause?
For some women, symptoms do ease after the transition is complete. But here's the honest answer: if perimenopause is turning up the volume on a nervous system that was already under stress, those patterns don't go away on their own just because your hormones stabilize. The women I work with who do the deeper nervous system work during this time often come out the other side genuinely changed, not just through the worst of it. There's a real difference between surviving perimenopause and using it as the catalyst it can actually be.
Is therapy really effective for perimenopause anxiety?
Yes — especially therapy that works at the nervous system level. Talk therapy alone has limits when anxiety is this physical. What tends to work best for perimenopause anxiety is a combination of somatic work (addressing the body's patterns directly), processing the emotions that are surfacing during this transition, and nervous system regulation techniques that give you tools for the moments when anxiety spikes. This is exactly what I focus on with clients in perimenopause.
Do you work with women outside of Chicago?
Yes — my practice is 100% virtual, and I work with women throughout all of Illinois. That includes Chicago and the surrounding suburbs — Evanston, Oak Park, Naperville, Wilmette, Hinsdale, Glenview, Barrington, Lake Forest, Highland Park — as well as women in Rockford, Peoria, Springfield, Champaign, and anywhere else in the state. You don't need to drive anywhere. We meet wherever you are.
What's a therapy intensive, and is it right for perimenopause anxiety?
A therapy intensive is an extended session, typically half a day or a full day, rather than the standard 50-minute weekly appointment. For perimenopause anxiety specifically, intensives can be especially powerful because they give your nervous system enough time to actually shift, rather than activating and then having to stop before anything resolves. We can go deeper, move through more material, and create a different kind of change than what's possible in weekly sessions alone. If you're curious, I'd love to talk through whether it might be a good fit for you.
