It is a bit of a myth that the degree of trans one feels is related to depth dysphoria with inevitability of wanting to self-destruct. I used to think I couldn't be trans because I wasn't into self-destruction. Well, my reading of the literature disabused me of that notion pretty quickly.
I learned to live with my dysphoria for quite a long time. It was always there, like a hibernating bear, never really asleep but not causing me harm. Some of us don't go down that path, but the dysphoria can reach a point where positive action needs to be taken, because that bloody bear just doesn't want to stay asleep

Good to see things are looking up for you finally. It will be an amazing journey of self discovery!
