Sisterly advice girls ??

The beginning of it all starts with the fact that my brother treats me like crap then sees it as if it's okay to do it, continues and it consistantly gets worse. Never wants to talk to me, even if we do, he always tells me to shut up, says I'm annoying or acts as if I'm a problem in life to everything. Speaking a word to him is like is should never be. He whispers to himself "shut up" as if I wont hear him or anybody else would. I confronted him cause I cant take his crap anymore. Him treating me like crap. How a brother should never treat his sister. He tried denying it to me face when I watched him act all bitchy and he tries to get away with the fact that he laughs at when i get yelled at for getting mad when he oversteps. I get yelled at for his actions, for me trying to defend myself. Even trying to defend myself my brother again just laughs like I'm a simple joke in life. Instead of telling a someone to kill yourself or themself. He simply tells me as if I shouldnt be alive by other actions and ways he treats me instead of saying those exact words.
