Hello Jasellebelle
Welcome to Susan's. Since this is your first post, in a moment a moderator will pop up to read you the rules, but hey, before that, something more useful

Your story mirrors that of many of us, so you're in good company here. As for the "OCD, low testosterone, ADHD induced dopamine craving" you're proposing, I think that's unlikely, and moreover you're rather mixing a bunch of probably unrelated or virtually unrelated concepts.
Gender identity is a complex mix of elements, and nobody on this site would venture a diagnosis, even though we can recognise the signs in ourselves. If you want to understand this part of yourself, the recommendation would be to see a therapist as your first port of call, and to explore both your gender identity and maybe your orientation as well. Therapy does not necessarily commit you to embarking on any kind of journey, but it might. This can be scary, but I'd say that finding out who you are would partly be a liberation, and it's certainly a wonderful thing to really know yourself. And once you've found out who you are, you still aren't obliged to change what you don't want to change, although many of us do.
While you say that you think you "just have body dysphoria and not gender dysphoria", perhaps this is true, but that would be best explored with a therapist. My feeling is that if you desire a more feminine body, you're likely to be venturin' into gender dysphoria territory, cowboy,er girl, er,whatever.

Many of us suppress our dysphoria spectacularly - we find other avenues of self-realisation if we can, and try to find a more "normal" place in life. Many of us don't want to transition at all. And some (like me) eventually get to a point where we must act. This doesn't mean that we spectacularly self destruct; but it means that we take steps to be who we really feel we should be.
All of this is a process, a journey with many stops on the way. My advice is to explorer yourself, slowly, with a good therapist, and remember that you are in control of the journey (well, most of the time). It's not necessary to make decisions until you want to.
Hope this helps
Julia
