I want to tell my Mom I'm moving out but there's a lot involved...?

First, is unemployed. She has not been working since August 2010. She has had an excellent experience as Administrative Assistant and Executive, but I honestly feel that he has not really been looking. MedlinePlus MedlinePlus I have 25 years and about a year ago, finally found a suitable job in the career that I would have. I've been paying your mortgage for that last year. Although it has helped me in the past, like a car, helped pay for college for me, etc. .. I feel like those are the things that parents make children love. Also, when she had the money. I understand you are going through tough times now, but it really has not been doing much to help themselves. She got a DUI about a month and a half ago, she is in all kinds of pills for depression and anxiety, and she seems to be agoraphobic. She depends on me too much to run to the store to buy their stuff, answering computer questions, spend time with her, and be the person bends over emotionally. MedlinePlus MedlinePlus To kind of go back to the mortgage thing is almost half of my salary, and I have been lax in paying my other bills, such as credit cards and student loans as a result. I think it's time I started to think and care for me. I feel like a burden to me financially and emotionally. MedlinePlus MedlinePlus Last Wednesday night I said I wanted to leave in August, thinking that would give him enough time to find something better. She got mad and yelled and not talk about it in a rational way. The next night was at a neighbor's house (which is like a mutual friend) and my mom came. She was just rude and obnoxious all the time and she was scolded by the neighbor who gave his opinion that only had to "let me go". In the end, my mother and I kind of made up, but then I said that I would stay in the apartment of a friend for a couple of days to let us both cool. She got angry and started to get ugly again. I told her effed up and left. MedlinePlus MedlinePlus I'm tired of the drama and the lies and over-reliance and I want out now (for what happened on Thursday). I wanted to speak tonight to have a "quiet conversation", which ended up being mostly explaining how she did all that he did for me and that I should help even though they have no money or credit. I said I'd think about it. MedlinePlus MedlinePlus After the long description yet condensed, would really be so terrible to move in August? What if I moved now? Everyone else in the family says I have to keep going, but I wanted unbiased opinions. I realize my description is not really all that goal, but I tried to be as objective as possible (believe it or not, the above description is more objective than the other being that). MedlinePlus MedlinePlus I hope everyone can get an idea of ​​this.
