frustrated. but what to do?

MY BROTHER IS AN INSENSITIVE BITCH.
I DONT WANNA LIVE WITH HIM ANYMORE. ITS LIVING HELL.
Its harder and harder to feel happy these days. I dont know what to do anymore. sometimes i feel so helpless i tear up.
life sucks. :( why must life be so difficult? Why must you do mean things to me on purpose? I have feelings too.
I find this all so unfair. why me.
