You're doing what healthy kids from troubled homes do: Be involved in lots of good things so you can spend less time at home. At home, pay attention to when your mom is at her worst, and take steps to avoid her. (Take a shower, go for a walk, study at the library, etc.). When she's in a bad way, DON'T TAKE THE BAIT. Don't argue with her. Instead, go to the bathroom, don't respond, offer to make her tea, change the subject, etc. Also, talk to a smart adult about what's going on or, better yet, perhaps you could see a therapist.
