Drama Queen is at it again

I'm getting to the point that I can not deal with my mother. She's bipolar, been diagnosed, but refuses to follow through with any treatment. She goes on and off medication, refuses to follow through with counseling, takes everything out on me, and I mean everything, the wind could blow the wrong way, and I'd get yelled at. My dad gave us $1,000 for earnest money for a house since we are trying to buy one. What does she do? Get mad and throw a fit because he gave us the money and won't pay her bills. Well, she gets a check every month, she can pay her own. They didn't have enough money last month to pay their house pymt, so she goes on shopping sprees, she has no concept of money at all. She gets mad every time we move, get extra money, anything bc she feels as if she should get to move, or we should give her money. She's jealous bc Nathan takes care of me, pays my bills, buys me nice things, a new ca when I want one, jewelry, tells me if I wanna work I can, but on his days off,etc. She "claims" that she isn't jealous, but I know different. The other day I met her and my dad to get the money, and she tells Bubba she's not gonna see him anymore bc he got mad at me bc I told him to buckle up. She takes everything out on me. But the fact she's focusing her anger on my kids is too far. She has never had to do things on her own. She went from parents to hubby #1, back to parents to my dad. She's never had a man do for her what he does for me. Nathan is amazing. We have worked for everything we have, we may not have much, but we don't want for anything either. She's jealous of people who get food stamps, jealous that he brings in over $5,000 a month, jealous I got the Jeep, she's not happy for me at all. It's getting to the point I'm not gonna be around her again if she keeps it up.
