Am I bound to an admission of fault if I had documented head trauma, a concussion and statement was given before hospitilazation and satabilization?

I was crossing to catch a bus, wet road conditions cars parked along side of the road, cross light must have changed or been in process of changing as I was crossing. I was hit by vehicle. Severe injuries, multiple broken/fractured ribs concussion, partial collapsed lung and pelvic fracture. Police report stated I admitted fault but have no recollection of admission or interview, two witnesses both not very favorable, yet since their insurance is required to pay my medical bills am I not entitled to some sort of financial compensation as well? Missed work, rehabilitation, mental and emotional problems related directly to accident
