You can't make yourself want to be a girl. It just doesn't work that way.
Sympathy? It depends on how you look at things. I refuse to see who I am as entirely a curse or a problem - so I don't go around feeling sorry for myself. I am just me. We've all got problems we have to deal with, so you just try to make the best of the situation. Things could be worse - I figure I could have been "intellectually mild", had a non-working body, a terminal illness, mental instability... any number of bugs some people get lumped with. Sure, it doesn't make GID any less sucktastic to deal with, but I find it helps me maintain some perspective.
Also, I've had oppertunites to see and participate in society from an angle that non-trans people never have, and never will. There's something to be said for that.
I did my "girl" time. I shut up and tried. I didn't even try to be the girl society wanted me to be (well, not for long), I tried to be one I could live with (however miserably). I managed to hit "transition time" free of kids, marrage, relationship, etc to deal with - but I've seen guys who haven't been so lucky.
