These are my experiences as well - estrogen helped my mental health more than anti-depressants, running / exercise, therapy, meditation, or literally any other intervention I have tried.

It is maybe comparable to taking drugs, tbh - my overall mood is much better, I am life-affirming, etc. and all of that happened before I was seen as a woman or my body changed. I swear it’s something to do with the brain not working well on the wrong hormones.
