Perimenopause is a mental health crisis for millions of women. And almost none of them know that’s what it is.
They think they’re falling apart. They think they’ve become someone they don’t recognise. They think, and this is the one that breaks my heart, because I experienced it, that it’s their fault.
It isn’t.
Here’s what’s actually happening.
Your brain is a hormonal organ
Estrogen isn’t just a reproductive hormone. It is deeply involved in the regulation of serotonin, dopamine, and GABA, the neurotransmitters that govern your mood, your motivation, your ability to feel calm, and have a sense of self.
As estrogen fluctuates and then declines through perimenopause, so does the stability of those neurotransmitter systems. What that looks like in real life is: anxiety that appears from nowhere. A rage that feels disproportionate and frightening. A flatness, a grey fog, a loss of the things that used to bring you joy. Crying in the car for no reason you can name. Lying awake at 3am convinced something is terribly wrong.
These are not character flaws. They are not a nervous breakdown. They are neurological symptoms of hormonal change, and they are real, measurable, and treatable.
What the research tells us
The risk of depression significantly increases during the perimenopausal transition, not because women are mentally weak, but because the brain is genuinely going through a period of neurological recalibration. A landmark study published in Archives of General Psychiatry found that women were significantly more likely to experience depression during perimenopause than at any other point in their adult lives, even women with no prior history of depression.
Read that again. No prior history. This is not old baggage resurfacing. This is biology.
What makes it worse, and what actually helps
Chronic stress, poor sleep, blood sugar instability, ultra-processed food, isolation, and a nervous system that never gets to fully rest all amplify these symptoms. They keep the cortisol high and the serotonin low, at exactly the time your brain can least afford it.
What helps, genuinely, evidentially helps:
Whole plant foods. The gut produces approximately 90% of the body’s serotonin. What you eat feeds or starves the bacteria responsible for that production. A fiber-rich, plant-based diet is one of the most direct ways to support your mental health from the inside out.
Consistent sleep. Every mood regulation system in your brain depends on it. We talked about this in previous articles I shared on Substack, if you missed it, read it, it will help!
Movement, but not punishment. Gentle, consistent movement reduces cortisol, raises endorphins, and supports neuroplasticity. Walking, yoga, swimming, dancing in your kitchen. Whatever makes your body feel like yours again.
Connection. Isolation amplifies every symptom of this transition. Being witnessed, by someone who understands, who doesn’t dismiss you, who says “yes, this is real”, is genuinely therapeutic.
Talking to someone. If you are struggling significantly, please reach out to a mental health professional. This newsletter is not a substitute for that. What it is, is a place where you are believed.
You are not going crazy
I know I say this a lot. I say it because I needed someone to say it to me, when I was in the middle of my own collapse and couldn’t find the words to explain what was happening in my body and my mind.
You are not too sensitive. You are not too much. You are not broken.
You are a woman in the middle of one of the most significant neurological and hormonal transitions of your life, and you deserve support that actually understands that.
Mental Health Day is one day. But this conversation, this is one we need to be having every single week.
If what you’re reading here resonates, I want to invite you to something bigger. In January 2027, I’m opening the doors to the Pause on Plants Inner Circle — a programme for women who are ready to stop surviving this transition and start truly thriving through it. Live calls, real community, real support. Women coming together as the sheros of their own health.
Applications are open now. Spaces will be limited.
