Anger getting worse

So, here's a little background. I play American football, attend school, play video games, etc, etc. Over the past year or so, my anger has gotten worse. I had some attitude before, but i dealt with it pretty well. But now, I have holes in the walls of my room from punching them, I consistently argue with my family members, friends, and peers, and i'm getting in trouble in school and athletics, for not being able to keep my mouth shut from things that I used to be able to ignore, and punished in practice for getting into full-on fistfights during practice. I am running out of options, and I now find it harder to restrain myself and get out of bed every morning with a smile. I'm starting to fall into a depression and can't maintain social relationships. I need some help/advice.
