As someone who has been there before and as someone who knows that every case is different, it really does help to have an ally or two in the battlefield that is school. A while after I started High School, when I was about 14, I realised that I was gay and that I was crushing for a guy in my classes. It was hard for me to be around him without picturing the two of us together in a crowd or together alone, most of the time it was alone and it got even harder when we had to do a project in Human Biology about the human reproductive system. Oh Irony, how it burns.
So after countless hours together, alone and with it being close to the end of school, about 35deg C in a classroom with no A/C, we were not wearing much. Then after a while of in-visioning him naked and staring at his crotch, he noticed that I was...."At Attention" talked to me about it and I told him everything. He was nice about it. He didn't judge me for it and we we're friends afterwards.
A few months later, one of his "Yeah, Boy!" crew saw me in the City with my first boyfriend, who luckily didn't go to my school. Then the next day when i rocked up, I had everyone in the school calling me a Faggot, Aids Fucker, Queer, Shit Stabber, all those generic, idiotic names. When I was walking home from school, I met up with the rest of the "Yeah, Boy!"'s and got beaten with a steel pipe, tied up with a bike lock, spat on, pissed on and had rocks thrown at my head.
Crush came along and saw what was happening and took a crowbar that was about to be the next thing to hit me, and bashed the original "Yeah, Boy!" over the chest. He told them to back off and the rest of them did. I don't know what happened to him. I've lost contact with everyone that I knew there. Being the First "Fag" at a Catholic School kinda makes your friends lose your number.
The moral of this, if there is one, is that High School is hell for everyone. You get beat down (Metophorically) all the time. All you have to do is get back up. Once you graduate, you never have to see any of those people again. All the people I know that were successful in High School are now speed addicts, teen parents, in jail or all three. There is light at the end of the High School Tunnel, no matter how dark it gets.
