Well it's understandable that you are worried about driving again after what happened.

Maybe an idea to have someone else with you in the car, the first time you go back to driving, someone to calm you down.

Try and use things to keep you grounded while driving. I have a marble in my car that rolls around and taps when I go round a bend!..............It helps to keep me in the here-and-now.

Hope you have a T to share this with.

Take care.
