This thread has been incredibly helpful and one of my tipping points, so thank you all for that. I have begun transitioning in many ways already (my behavior, my appearance), but really transitioning physically has been something I am a bit afraid of. I still am, so very, very afraid.
My family isn't the most conservative one, but I know my mother will be ashamed and want to hide my "secret", my father will most likely not accept this and my other relatives, well, they will judge and question. This makes me afraid, but also determined. Before I thought about transitioning, I'd never have considered going against their judgement in anything, I was really a push-over; and now that I know this really rings true to me, and that this is something they will have lots of prejudice about, my determination to walk this road even if I know many will not accept me makes my decision feel so true and real and dear. Somewhere along the way I have begun to accept myself, I've never felt that before, and now I do, all thanks to understanding that I am transgender.
The other, a bit shorter point and realization was that as a girl, I would never find happiness. Especially in romantic relationships: even if the person was right and the feelings were real, I was always wrong and out of place, and I hated that. In other relationships, well, I don't have many feelings towards my relatives or any people I call friends. I have somewhat of a grim outlook on life and people. Transitioning, I think, means I could really relate to them all and build real relationships with them, not just something that always feels fake when there's this big, physical wall between me and the world and the wall is all others can see.
So there are my points. Again, thanks for all these stories and thoughts. 🙂
