You are standing in your kitchen and your heart is going.

Nothing happened. Nobody said anything. The dishwasher is running and the dog is asleep and your chest feels like you just missed a step on the stairs.

You have started dreading things you used to do without thinking. Phone calls. The grocery store on a Saturday. A work email with no subject line.

And somewhere in the last year or two, you quietly decided this is just who you are now. An anxious person.

You are not. Something changed, and it is measurable.

Sixty percent of us. Nobody mentions it.

Around 60% of women report anxiety during perimenopause. It sits right up there with fatigue and brain fog as one of the most common experiences of this transition.

And yet almost no one is told to expect it. You get warned about hot flashes. Nobody warns you that you might stop recognizing your own nervous system.

What is actually happening

Two things, and they compound.

You lost your brake pedal

Progesterone is usually the first hormone to fall in perimenopause, often years before your cycles get strange. Your body converts it into a compound called allopregnanolone, which works on the same receptors in your brain that anti-anxiety medication targets.

Read that again. You have been manufacturing your own calm your entire adult life.

When progesterone drops, that buffer thins out. The same amount of stress now lands harder, because there is less between you and it.

That is why the anxiety often feels untethered from anything real. It is not a response to your life. It is the absence of a molecule.

And estrogen stopped being predictable

Estrogen helps regulate serotonin and other neurotransmitters involved in mood. In perimenopause it does not decline in a smooth line. It swings, sometimes wildly, sometimes higher than it ever was before it crashes again.

Your brain is trying to run on a power supply that keeps surging and browning out.

Why this anxiety feels different

Women describe it in ways that sound nothing like the anxiety they had at 25:

  • It arrives without a trigger, often first thing in the morning or at 3 AM
  • It is physical before it is mental. Racing heart, tight chest, a jolt of adrenaline
  • It comes in waves that track with your cycle, worst in the week or two before your period
  • It attaches to things that never bothered you before
  • It lifts completely for a few days, which makes you doubt it was ever real

That cyclical pattern is the tell. Anxiety that rises and falls with your cycle is a hormonal signal, not a character trait.

The part that makes me angry

A woman walks into an appointment and says she is anxious. She is 44.

She walks out with an antidepressant and no one asked about her cycle.

SSRIs help some women, and there is no shame in taking one. But prescribing one without ever asking whether the anxiety is cyclical, without checking where she is in her transition, without mentioning that progesterone exists, is not treating her. It is quieting her.

You deserve to know what is actually going on in your body before you decide how to treat it.

What actually helps

Address the hormones first

If a hormonal shift is driving this, the most direct answer is hormonal. Oral micronized progesterone is calming by design, which is why it is typically taken at night. Stabilizing estrogen smooths out the swings your brain is reacting to.

Where to get it

You do not need to wait three months for an appointment. Both of these work the same way. You complete a medical intake, a licensed provider reviews it, and prescribes if it is right for you.

Or browse everything we recommend for hormone support, including estrogen patches, DHEA, vaginal estrogen, Thermella for night sweats, and a multivitamin with DIM.

This needs a provider who understands perimenopause and will not tell you that you are too young. our free directory of 661 hormone-literate providers includes telehealth options covering all 50 states.

Support the foundation

Once your hormones are being addressed, the basics matter more than they used to. Protein, strength training, and consistent sleep are not small advice here, they are what your nervous system is running on.

The multivitamin I take daily is Daily GLOW by Dr. Michelle Sands, formulated around thyroid, adrenal, and hormone support. Our community gets 20% off. It is not a treatment for anxiety and I am not going to pretend it is. It is a floor, not a ceiling.

Fix the sleep, because it is feeding this

Anxiety and insomnia in perimenopause are the same problem wearing two outfits. Poor sleep raises next-day anxiety, and anxiety wrecks the next night. Here is what is happening at 3 AM and what to do about it.

What to say to your provider

Do not say you have been feeling anxious. Say this:

  • “This anxiety started in the last two years and it is new for me.”
  • “It is worse in the week before my period and it lifts after.”
  • “It is physical. Racing heart, tight chest, often when nothing is wrong.”
  • “I want to talk about progesterone before we talk about an antidepressant.”

Specific gets taken seriously. Vague gets a prescription pad.

The part I need you to hear

You have probably apologized for this. To your partner, your kids, the friend whose text you left unanswered for nine days because opening it felt like too much.

You have been treating yourself like the problem.

You are not anxious. You are under-resourced, at a chemical level, in a way that is documented and treatable and that nobody bothered to warn you about.

You are not crazy. It is your hormones.

Find a provider who will actually listen.


Not medical advice. Always consult a licensed healthcare provider before making changes to your health regimen, especially before starting hormones or combining supplements with existing medications.

You are not crazy. You deserve to feel Awake & Alive.
