Hi! i do'nt really know what to say, but keep your head up, do'nt let them pull you down, you know that the girl in the clip is not you, GOD knows the girl in the clip is not you, your friends know the girl in the clip is not you, and your parents knows the girl in the clip is not you, so if no one else beleives you, so what, they do'nt feed you, they do'nt put cloths on your back and they do'nt put a roof over your head, so who cares what they think.
As long as your parents, friends and GOD knows it was'nt you thats all that counts, they are the only ones who matter.
I hope you feel better, may GOD bless you and see you through this hard time.
