I totalled my car right after my insurance cancelled. My friend and i are severly injured. What do i do?

Basically i may be charged with a DUI. Don't think so though... For insurance i found out it was cancelled when i called to make a claim. They said they mailed it to my old address and sent me and email. I never receive and email but i don't check it that often. My friend and I rush to the hospital via ambulance and both got MRI's. He ended up with a fractured neck that will heal in a few months, but he has a lot of dentistry to go. I believe that I will have to hire i laywer and try to lower anything as much as i can. Otherwise I have no idea what to do or how to handle this. Also making 9.25 an hour doesnt help either. Any ideas?
