I agree with A. A T could be very helpful for you, especially in learning how to not enable him so much. My parents always made it clear that I could always live at home, but I wouldn't want to. Their agreement, I would be provided:
Shelter: a tiny trailer out back; I would be responsible for emptying it's sewer tank, heat would not necessarily be provided although they'd make sure I had enough blankets to not freeze to death.
Food: Rice and Beans and occasionally fruit and veggies
Laundry: Once a week I would be able to come in and do laundry.
These were all provided if I chose not to work.

If I worked I would be allowed to live inside if I paid rent and contributed to buying groceries and cleaning the house... else the trailer was always an option. Also, rent would be about half price of what it would normally be so I could save up for my own apartment.
