I am addictied to my x-box 360 i need help?

My mom only lets me play it on the weekends because of school work. I am doing better but my mom needs proof. I can't get any right now. After i do my homework i get bored and it feels like i am going insane. I get moody and i want to explode. I feel depressed. Please tell me something i can do to make it better besides playing outside ( blieve me i would but it is snowy and super cold and wet.) or playing games on the computer they just don't entertain me like Halo 3 or Gutair Hero III.
