That's about all I can think of too, what ML said. My parents (well, my mom-my dad doesn't know) aren't against it at all but she doesn't seem to get it. She still calls me a girl, calls me my legal name from time to time, stuff like that. That's a crap situation though, it's bad enough feeling messed up and depressed, with all that BS on top of it?
Good luck, man. Definitely try to avoid those situations as much as you can, if only for your own comfort.
