No wonder you're scared of driving.

I'm so sorry asking about what you meant by 'riding'. I'm Australian and that term as riding/being a passenger isn't familiar to me.

If you sustained a concussion or brain injury in your crash then there may be people who have similar experiences in the Traumatic Brain Injury and Post Concussion Syndrome Forum (link posted below). You will find good support and advice there from people who have gone through experiences such as yours. It's quite a busy forum and the members who post there are very helpful and understanding. Anxiety issues are not uncommon.

I wish you well.
