Sorry to hear about your issue and that you find it bad enough to give up. I wont speak to anything you did, didn't do, or could have done, since I'm not in your shoes.

However, you had a car crash with injuries and are facing hospital bills. This is a clear case for hiring an attorney, because it's serious $$$$ stakes.

Also, if you happen to own an insured car, you can also process the claim through your own insurance, which (in most states) is obligated to cover your injuries and treatment, and represent you in any other damage claims against the other driver.

So, my advice. Purdue your claims aggressively, then recover, then take your time before making any life decisions.
