Whether you need transition or not is irrelevant, since I think right now you don't need transition, but to work on your personnal life. What you say quite resembles what I felt when I was 20. And when I was 20, even if I needed transition, I had a lot more important things to do first : find a balance, find happiness, find more things about myself.
I'm not suicidal either - I used to cut myself when I was 17, but I never seriously thought about suicide. But for most of my life, I didn't really mind dying. I was never an happy person to begin with. So I can quite relate.
Maybe today you're not happy, but keep looking. It's boring and long, and sometimes you wonder if there's a point, but you'll end up getting a lot better at being happy, one day. Happiness is something that you build. Find what makes you happy and focus on these. Forget the rest.
I really get your "what's the point of all this ?" feeling. I'm 27 and transitionning, right now, and I don't give a damn about being seen as a woman. Most of the things normal transpersons do are just not made for me at all. I came to realize it was totally irrelevant. But I need the body, and that took me quite some time to realize. In fact, more than time, that took me a lot of experience in real life.
So whether you need some transition or not, I don't know. Given what you say, most likely not. But even if you do, I can safely say that right now, the choice you make to get away from any trans activity and just live your life seems to be the right one.
