I can’t anymore

I’ve been bullied all of my life for little things that I think make me important. Constantly I try to fit into other groups of people (like the cool kids) and make friends. Some of my friends are apart of the cool kids group but we aren’t together like that. Whenever I get bullied I stand their and don’t defend myself. I know that silence is the key but sometime I just want to kill the people that bully me.

So what should I do? Defend myself or not say anything? Please leave some comments down bellow I really need your help
