I'm pissed and need help

So I got pissed at my bf and tried to sneak out before I punched a wall. I also cracked my screen because I threw it because I was pussed. And my mom caught me getting out. She called me a f***ing liar and that I'm dead and all this sh*t. Even my brother said that she was being a b**ch about it. She said it's a f***ing good thing we got in a fight. What do I do? I can't leave for the weekend and am gonna break something. I can't even take my brother where he needs to go. How can I help this anger?
