TITLE: Long-term planning on becoming more independent. Need advice about income, bills, and other things I have no idea about.
POST: I'm not being kicked out or anything. I am currently disabled. I don't want to stay that way forever and am in the process of looking for some work I am actually capable of doing. 

Anyway, I live with my more severely disabled mother. Together we make a somewhat functional household. I've been working with my doctors and in the coming years would like to see if I could reenter the working world with their help. Eventually, I'd like to earn enough to not only cover my expenses but to take some off of my mother's shoulders as well.

I don't take this process lightly. I became disabled when I was 23 (was living with parents then) and now I'm 29. While I help pay bills and take care of the house, I have no real idea (or at least think I don't know) about the independence I'm looking into. 

Obviously, I'll need housing, electric, water, groceries, gas for the cars, and phone which is what I pay for now. But what else should I be aware of? What level of income could cover those as well as health insurance?
TL;DR: 
I'm a disabled person trying to gain my independence and get back to the working world. What expenses and financial issues do I need to be aware of?
