Police response from being hit by a car

I was cycling across a roundabout last August when a car pulled out, not looking right, I went over the bonnet, hit the road and then my world changed.

Fractured L2 vertebrae, still in pain 6 months on and I received this in the mail last week, i am absolutely fuming.

There were multiple witnesses at the scene, which the police attended, and had statements taken then before an ambulance arrived and took me to the hospital on a spinal board where I spent a few days before being sent home in a back brace. All in I was off work for 2 months and to this day I am still in pain.

Does anyone have any advice on what I can do? The driver has ruined my life with no recourse.
