<human>: So my parents are in a process of divorce. My mom, who has extreme OCD/depression/bipolar and refuses to take medicine to make her better, is becoming an extreme problem to me. She gets in this state of mind(complete rage) where she justs punches hard, sand I even had a cop come out to my house because she was jabbing me with a key and he basically told me to toughen up and do some chores around the house. I'm in the IB program, so any time I have is limited by homework, projects, etc... which makes it hard to do things. She is a pig. I won't lie. She lets dishes pile up for weeks, same with laundry, and she doesn't do the simple upkeeping required by a mom. She lets my 4 year old brother go to bed at 1-4am and she'll spend the night playing on the computer. Now, she is very bad at keeping the house clean, which, theoretically would be easy since she doesn't work and only ~~watches~~ sleeps with my little brother most of the time I'm not at school. This is the main reason my parents divorced: my dad,  stuck between a rock and a hard place, cheated on her with several women because he wanted to stay for us and avoid this situation. I love my mother as my mother, but as a human I feel nothing for her, I really do try but it is extremely hard when your own mother calls you a fat ass/bitch/lazy ass punk. My dad knows how she is, but she's been taking most of his money so he can't afford a place in our county, he lives with his friend from work but stops by frequently. 
She has always been a control freak over letting me do anything relatively fun, I've missed out on cruises with my family, trips, and my siblings and I are even missing out on the 2012 Olympics in London because she wants to get back at my dad for divorcing her. We have food in the house, that's not a problem. Frankly, I don't know how he stayed with her for 16 years. I try to respect her but she makes statements so outlandish you'd think she invented the question mark.

Summarize the given text in a few sentences.
<bot>: My mom has depression that she won't get medicine for, plus she lacks common respect towards me and my siblings.  How do I deal with her in a positive way?
