It's great news! Finally you are on your way and you have the full support of your SO. This is just the best. 
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!
