I'll admit I did not read every post... I went from the first page to the last.
So I don't know how old you are, but you make this sound like a recent problem.
For me, it started when I was about the age were I became aware of genders. So maybe 4 or 5. And then I knew I was a girl. But my mom didn't agree. lol (I can laugh at it now...) So after letting me wear nail polish for a while, it was all over. I hated having my hair cut. I hated the clothes I wore. When I hit puberty, well that just sucked. Now I'm 55. I'm just deciding to do something about this. I was married for 9 years, and been divorced for over a year. This gave me time to be with myself and think. The divorced was not directly related to this, but this is always the underlying problem. I really wish I had done it at the very least in my 20s, but so it is.
How did I deal with it all these years? It wasn't easy. I just lived my life, and longed for a different one. Had several urges to commit suicide, but didn't. Had lots of anxiety and depression. And to this day I'm never really happy, unless it's related to female things. I'll buy clothes and stuff, but except on Halloween, never cross dress in public. I did dress very androgynously in high school and after, including wearing nail polish, some girl's clothes (like tops and jeans), makeup and I had long hair. That made me feel more like myself. People thought I was gay, but I like girls.
(so I guess that makes me a lesbian after all!)
At this point in my life, and accepting that I'm going to start this journey, I can look back and see all the problems I had by not trying to do something about it, or even tell people. I had therapy for the anxiety and depression, and the one time I tried to say why, it was dismissed.
Now I have been telling a few close friends, and it feels really good. My 22 year old son lives with me, and lately I have been painting my toe nails black. lol He looked at me funny, but he knows I'm different, so he just said I look like a Goth from the 90s. lol (I have longish hair with a bright blue streak in it too). People just think I'm a musician.
But I'm happy to be starting this. I never did fit in with guys. With few exceptions, my close friends were always women. When I was a teenager, the boys I knew would be playing sports, while I was making my own clothes, or playing guitar, etc.
So listen to your feelings. Find out who you really are. Some of us get stuck in the wrong bodies. These days it can be "fixed".
Don't wait as long as I did. Talk to a therapist who specializes in gender issues. They won't laugh at you or judge you. The one I'm going to see has two grown transgendered children!
