Hi, you're problem seems like a similar problem to the problems faced by sikh children today. I'm 16, and i've seen the "incrowd" harass a lot of the other students in the class but you just have to keep your head up. If you feel weak right now at the age of 15 then how will you feel when you're 25 and someone tries to take over your job or whatever else. You just gotta look those tormemtors straight in the eye and ask them what's your problem with me? This will probably take them some time to think about the answer and maybe even stump them. Society's evolving by the minute and maybe these people who harass you gotta face reality: harassment is wrong. Anyways i hope i haven't said too much to confuse you but nothing in life comes for free you have to stand up for what you believe.
God bless
Later
