How can I settle my medical expenses?

I was diagnosed with p.t.s.d severe depression,anxiety , long and short term memory loss, from the airbag knocking me out and burning my face and arms. I had 4 epidermal; 3 in back 1 in neck and then recently had knee surgery. They cleaned my knee and fixed my torn meniscus, had physical therapy for my back and knee twice. 6 months of chiropractor because of bulging disc in my back and neck many trigger point injections bin on pain medicines for 6 months and now they wanna give me cervical factorial injection and then possibly surgery for my neck. I'm currently in debt from this and in collections and the total bills including are is almost 100,000.00. I was hit head on from someone heading in my lane of travel he was issued 2 citations careless driving and failure to maintain lane. I'm really praying to get money because loss of work, loss family time and couldn't take my nephews trick or treating and many other loses including lose of intimacy, sexual impotent, many other side effects...
