Hi, you might want to try low dose estrogen. I've been on it more than 5 years and still present male. Very few people know. I've been on full dose for while now as well, and still no one notices. I work at hiding it, but its not that difficult.
Just because you're on HRT it doesn't mean you you have no options as to what happens next.
The mental effects though are enormous. You probably can't realize if you've not experienced it. It might help a lot. It did for me. You can always stop it if you don't like how it makes you feel.
I'd rather not do it this way, but I have my reasons and made the choice.
I'm not sure if its the same, but I had an over the top sex drive and I'm sure now it was due to stress. It sure wasn't testosterone as it was very low due to another problem I didn't know I had. I only found out about that when I got a blood test just before starting HRT.
The way you describe it, giving up, is actually how I think and talk about my recent years.
I've tried to stop HRT so many times, due to family and other things. I kept coming back to it, and and I'm not even trying to stop anymore. I can't live without it. I felt great when I started HRT, and I did manage to stay on low dose a long time, but eventuality wasn't enough and I was making myself seriously ill with stress and depression. I really did give up then. It became very clear to me that I was going to die very unpleasantly if I didn't change. I sometimes look back and wonder how I managed to push myself so far.
So here I am, full HRT, no social transitioning, but I'm pretty happy right now. Life is good. I've no idea if it will last, or how long, but I really don't care anymore. I'll just go with it and see what happens. Next time though, if there is one, I'm not going to push myself to the limit before giving up. I'll lose yet again, and it's not worth it.
