<human>: Can you give me a shortened version of the text?

I've been wrestling with the idea of moving out for a long time. I'm 21 and work as a receptionist in Minneapolis for a luxury apartment business. I make $10 an hour, at a base of 30 hours a week. I've been working there for six months and because we're short staffed I've almost always hit around 45-60 hours a week with some great overtime. My best friend and I are eyeballing a few apartments in the cities that are around 900 or so a month, with us splitting the bill down the middle. I bring home about 1,300 monthly when I'm only getting minimum hours.

I currently live at home with my mother and 22 year old brother. Both of us are taking a few years off of college (I have no college debt just yet to worry about) to save up money and get our ducks in a row. My main concern with moving out is not how I can manage financially, but how I can manage both my rent and her rent at the same time.

My mother is absolutely terrible with money. We live in a trailer with $580 rent, and she's always supported us with a boyfriend's income, or by borrowing money. She's been an artist her whole life and doesn't have many other job skills at 57 years old. She's also recently in remission for breast cancer and I can't let her overwork herself since she's at risk for relapse if she gets too stressed. I feel responsible for her since she's very scatter-brained and I'm concerned that she can't make it on her own since she's never had to do so before. 

My brother and I pay most of the bills. She gets $700 a month for unemployment, but that won't cover the debt she's gotten herself into over the years, along with two cars and a huge electricity bill.  I think I make enough to survive on my own (especially with a roommate), but I need advice about how to deal with a dependent parent.
<bot>: Desperately want to move out of the nest, but don't know how to keep myself and my mother financially stable. Any advice for me?
