I was df'd but left a believer. Any time I faced adversity I felt as though it was a punishment. Maybe your problem with finances and insurance is causing you to feel that way too. ANd being alone in the world is very scary without friends, especially if you don't have the money to change your surroundings.
You will feel less lonely and more confident once you overcome difficulties on your own. Always remember that no matter how bad things are, they will change, and you won't be under these circumstances forever. Maybe picking up part time work will help you to save enough to move and pay for insurance. Perhaps you have a 401K you can cash in or have an income tax return coming. I don't know your financials, but there's always some way to dig yourself out.
