I have gone through it. Allmost the same situation, but when i got friends, started partying,drink,smoke,light drugs( all the other B.S. that "COOLEST DO" ). I did bullying all the rest school time, and i super enjoyed it.. Well teenager life isn't that easy, how others think. Also i feeled terrible when i got this anxiety problem. But u know, i super enjoyed making fun'n'stuff the weakest, but i SUPER SUPER SUPER enjoyed, making fun of another "bully's". So i came to the conclusion that I am not so bad at all , regret nothing.
