I agree with everyone, he dosen't seem like a real friend, he thinks he has a power thing over you and is abusing it (maybe he so immature that he thinks that this is cool) but you are being bullied, I would do what everyone else suggested, work on your confidence, make new friends, contact local groups and start making friends with them,contact "outhouse" and remember that this isn't the end of the world, millions of people out their have gone through this so your definitely not alone. And as always Gaire is here. Welcome by the way
, The important thing is to take this power away from him, this is something only you can do, but remember you have all the support in the world, he actually dosen't, he only believes he does, cause it based on your fear. If he outs you, deny it, (or confirm it, what ever your comfortable with) he looks like the smallmind gobshite either way. (cos that is all he is)
Best of luck on your decision.
