He's really pissing me off!?

This is probably seeming stupid to you but I'm really reaching my limit and killing myself is seeming really good right now. My dad is short-tempered and such so it's real easy to piss him off (isn't that what it means?). I got back from camp yesterday and I took karate, which means my arms are really sore. I wanted some ice cream so when I tried to scoop it out, the ice cream box/container flipped out of my hands and slid across the kitchen floor. He was all upset and said, "It's your fault! It doesn't do it on it's own! You had to have helped it!" Why is it always my fault? When I went to camp I missed my mom and brother slightly but I didn't miss him in the least, and when I got home I didn't greet him, so I'm not attached to him at all. Help... Please?
