Friends Ran Me Over

When I was a teenager (10-15 years ago), my friends ran me over leaving me with serious health issues and trauma I’ve had to deal with over the years. At the time I didn’t love myself much, stayed friends with them, and was an athlete so I lied about my overall health to compete. When I returned I had a lot of success and relatively good grades, though I knew I was struggling in various way. I wouldn’t tell anyway because I felt like it’d jeopardize my athletics. At the time we had a claim for the pain and suffering, but it was pennies compared to what it should have been. My insurance company said I was 50% at fault and that my friend (the driver) lied about what happened. My family remained friends with them and their family, but the fact that they may have lied and I didn’t get much compensation, knowing how much it’s affected my life has been eating at me and the relationships close to me. Is there any way to pull up records or figure out what was said? I was young at that age and had no idea what was going on, while also dealing with a traumatic brain injury. I’ve been looking at everyone around me funny lately and if I was able to find out whether they lied or not would help me move past this. I never really started to deal with the trauma of my accident until a few years ago and so a lot of these things feel fresh. Any help would be appreciated because I have no clue where to begin to find out any info on my case or claim!
