I have had quite a bit of trepidation regarding support groups. Thing is, I think it could be helpful to reach out to more transwomen IRL, very loosely associated with my social group is an FTM but beyond that I don't really know other transpeople IRL, but I am not sure I would enjoy the experience. I have some strong opinions about how I want to do things, and my experience online has been that people who do things differently out of concern for me or to validate their own choices go out of their way to try and tell me I am doing it wrong and I need to do it like they do. This is unproductive to me. Online it is easy to handle, my online mettle was strengthened by playing Eve Online so much, that almost nothing can make me feel all that bad online, but IRL it isn't all that hard to make me cry.
I think that near Washington, DC there is more than one group for MTFs, but still I have doubts on if meeting other transwomen would be good or bad for my morale. I have some very supportive friends, of course they have no real understanding of what I go through they don't need to understand they know what I want and they know my "lady pills" as they call them make me even more emotional than before. So my worry is, not that I wouldn't get anything from a support group, but more I am worried about people not being nice, or judging me; perhaps IRL it is different but online I see so many people who are "->-bleeped-<-r than thou" and who are older and seem to have some abject hatred of younger people who are closer to passing (am 28 that is kinda young I guess), these sorts of social dynamics worry me, I don't think I could really deal with such attitudes face to face. Though to be fair SuzifromMD and ThePhoenix both seem really nice and live closeish to me IIRC, so they don't seem so scary.
