Nervous about High School, because I'm bi.?

Well, June 8 was the last day of my entire middle school education : / Now it's summer, and I'm hanging with friends, getting ready for the beach! :) So anyway, I will be a freshman when school resumes. And at my middle school, I was the only person out of the three grades there who was in the gay community. I do know for a fact that there are other gay people already at the high school, and there are other gay people in my grade at other middle schools, so I'll probably make some gay friends when I go there. But there are things I'm worried about. First of all, the bullies. However, this high school has a discrimination rule where teachers & students CANNOT make gay couples stop kissing or doing any kind of PDA, because it files as discrimination, and the school can actually get sued simply if a teacher tells a gay couple to stop making out. But get this- the teachers and students CAN tell STRAIGHT couples to stop doing ANY PUBLIC DISPLAY OF AFFECTION!!!! It just doesn't make sense. I mean, I'm bi, and I'm all for equality, so I still believe straight couples should be able to kiss their partner in the halls, just like gay couples can. And I actually haven't heard any bad cases of LGBT bullying there, except for my cousin. My cousin is straight, and he gets made fun of there because people think he's gay just because he has a high-pitched voice. So it makes me wonder, if a STRAIGHT guy is getting made fun of, and he's not even gay, then just imagine what's in store for me. I can stand up for myself and I do it on a daily basis. I have high self-esteem, and I'm proud of who I am. So it's not a major problem. Just all those things you see on the news about gay teens committing suicide or getting murdered freaks me out. I guess I should just let this burden not bother me. After all, high school has enough worries, especially when you're a freshman. And I don't need to be worried about anything more. Just tell me what you think. Thanks!
