You don't feel that strongly... yet!
Just kidding :D
It's not transition or death for everyone. But there should be a feeling stronger than "Mneh, yeah I'd like to be a girl" :P I mean... if I had a significant other and children to live for I'm pretty sure I wouldn't have been so selfish as to consider ending it all. But I really didn't have much else.
Find out what's true for yourself. You'll go crazy trying to define who you are by comparing yourself to everyone else.
But if you don't like your junk... that kinda tells you something, doesn't it?
