Plenty of sound advice.
A couple of bits to think about.
Keep a diary of pain and how you are feeling. Photos on any injuries, bruises etc.
Photos of the accident site and annotated diagrams of what happened etc.
Write down what happened whilst its still fresh in your mind.
Get your bike looked at by a decent bike shop. Get them to check the frame, wheels, the lot.
List damage to any clothes, shoes and gear you were wearing at the time. Consider replacing your helmet, even if it appears unmarked.
Try and contact the witnesses and get statements off them, don’t assume the police have done this.
The driver may well have been upset and shaken up at the time, but they can turn into lying SOBs when they realise how much it could cost them to replace your bike and kit etc.
Hopefully it’ll be fine and you’ll be reimbursed for any damaged items.
Rest up and I hope you’re feeling better soon.
