I stay involved in the trans community for a few reasons:
1. As someone who's been transitioning for a long time and thus am basically at a point that a lot of people would consider the "end," where I'm more or less at the end of the social transition and hormonal changes, I can answer a lot of questions that people who are early in transition can't answer. I remember when I was earlier in transition one of the biggest frustrations was that there were so many people early-in-transition and so few voices of experience.
2. I have anxiety issues, which makes making friends in real life difficult due to me constantly being afraid of their judgment, so I tend to tense up and be super-scared of anyone clocking me or seeing me as an outsider. But in trans spaces I don't have those same anxiety issues, because instead of always being the ugliest girl in the room, and the only one who's so tall and large built, in trans spaces I'm just me. Because when I know I'm surrounded only by trans people and their allies, I'm obviously not worried about anyone judging me to be lesser or unworthy of being seen as a woman. I'm still working on this. But until such a time that my anxiety is under control, I need trans spaces to give me a social outlet where I can just relax, meet people, and feel normal.
3. I like being an advocate. And staying in trans spaces gives me a lot more examples, a lot more stories to tell, and a greater understanding of the needs of the entire community.
4. Perspective. It reminds me that the things that I want to do, and the way I'm feeling, is normal. And it lets me compare/contrast my desires with the desires of others who have gone through the same thing.
5. Because I have friends there, of course!

And I love being with my friends!
