I only started HRT about a month ago, but I'll put the things I've noticed so far

Pluses: My skin and hair isn't oily anymore. I didn't have much acne before HRT, but now I don't have any. My hair and skin overall seems healthier too. I use to take anti-depressants don't need them anymore. Now I'm not sure if it's the hormones or just my life is going better now. Whatever it is, I feel happier now, less anxiety, and just overall feeling great

. My sex drive has dropped considerably too.
I was already emotional before HRT, so no changes there. I actually got better at "controlling" it before I started HRT, so I'm not an emotional wreck too often

. I tried to "hide" my feelings, and my feminine side when I was in my teens, and I was able to let myself "be" before starting HRT also. I think a lot of it is being able to accept yourself, not necessarily that HRT brings it out.
Minuses: None yet

Although I'm interested to see if I gain weight, my family and friends always say I'm too skinny, so maybe it's a good thing
