There is !asktransgender@lemmy.blahaj.zone. Those of us who watch the local feed will see it.
There’s also not so many posts in most communities that you need separate spaces to ask questions. So any community related to the question should be fine. !LGBTQ_plus@lemmy.blahaj.zone is probably the most general one here.
From my understanding how a body responds to HRT is basically down to luck. Changes can be large, small, fast and slow. The chances of seeing large changes might decrease over time but is probably never zero.
One thing to note is that we are often our worst critics. We see all the things that haven’t changed or things changed so gradually that we never noticed. These changes can be obvious to those around us while we remain blind to them.
The question I would ask is do you want to continue taking HRT? Is it causing you an undue burden or harm? Will stopping make you feel better? Will stopping make you feel worse? These are probably things to discuss with a doctor to help you come to a decision.
