I'll try to answer this one on a broader point. You're clearly young and are still struggling with fitting-in and the throes of growing-up. I'm a lot, lot older, and in many ways envy your present problem, I only wish I had your youth with what I know.
Here goes...
Go on call me gay, call me whatever you like. You choose the insult. You don't like hockey' skates for kick-off. At my age it'll be water off a duck's back, and all in a way it could never be at 15. (I'm old duffer by the way) So, why you ask will this be so? Because I realise you don't really care what I think, you're too wrapped-up in your own world. So you may vent your opinion of me, but why should I really care what you think? I know for a fact you don't really care what I think, so I'm not going to give you the head-space for your thoughts, I've got my life to live, not yours. And do I want to associate myself with someone that's bothered their head to have a pop at me? I don't knwo what you called me jsut then, but I assure you, now you've called me it, my opinion of you just fell through the floor, so you're free to go.
Me, I'll have a quite chuckle.
So when I insult you, what should your response be now??
Am i worth it? No. You don't care one scrap what I think - now turn that round.
Go over that in your mind. Read it 2-3 times if you need to. I hope it helps.
