@KittyMeowMeow,
From what I read in another thread and post or yours, you are still relatively young (you mentioned the GSA* at your school). So life isn't near as bleak as it currently may seem.
Fluid sexuality is a rather new concept to many folks, so give them time to learn. Get information out to them. Help them along, don't let them get the better of you.
Just as it has taken far too long for the masses to accept homosexuality and bisexuality, your sexuality will at some point meet greater acceptance. Stand tall and be proud of who you are. Friendships and relationships will likely happen if you show yourself to be comfortable as you are and don't try to force others. Allow them time to get to know you and realize you're a regular human just the same as they are.
