When estrogen drops, everyone talks about what it does to your body: Hot flushes...Joint pain...The visible things you can describe to a doctor and get a prescription for.
But nobody tells you what it does to your brain.
Specifically - to two chemicals that are directly responsible for your capacity to feel pleasure, connection, motivation, and joy.
The first is dopamine. It's your brain's reward chemical. The one that creates the warm pull toward things you love. The one that makes you want your life - your morning, your weekend, the person sleeping next to you.
When estrogen drops, dopamine signalling collapses. But it doesn't happen suddenly. It's more like a radio station fading as you drive out of range. You just notice, one day, that the music has stopped!
The second is serotonin. Your brain's stability chemical that keeps anxiety quiet. The one that makes you feel that things are okay and that you are okay.
When oestrogen drops, serotonin drops with it.
This makes the brain compensate by going louder on 'threats' - more prone to the 3am panicking, the anxiety that fires suddenly, the dread that can't be explained.
Low dopamine + Unstable serotonin. A nervous system permanently running on empty.
Result: emotional flatness punctuated by anxiety, irritation, and rage - with joy, warmth, and connection becoming unreachable.
