I don't know about Craigslist for finding lodging - but maybe check with local churches or colleges perhaps and see if they have families who rent rooms to students -
Your plight is familiar to me as I relied on my abusive parent for college funds, then was at her mercy about not finding the type of job in the interim years she thought was "appropriate." You can't win.
A good plan might be get out of their realm of abuse and get some safe little place to think and regroup.
You aren't what you do remember. Whatever job pays your bills - it's not the definition of you. I have encountered some of the sweetest most resolute folks I know who are custodians and housekeepers - their inner core is deeply grounded and unassailable.
Good luck with your housing search. Don't go to any Craigslist address without a friend. And make sure someone knows where both of you are going. I just found an amazing Choc Lab girl to live with me via CL... . so it has its merits... . but we all hear too many horror stories too.
A good life is waiting for you. You just have to track it down.
