Anxiety after car wreck

I have a history of anxiety already but it’s been worse since I had a car accident a few weeks ago. I’ve been having panic attacks every time I have to drive or just randomly sometimes. When I go to sleep I have dreams of the accident and the sound it made when our cars collided. My car was totaled but I’m grateful to be alive and that my daughter wasn’t with me when it happened. Has anyone else experienced this and how did you get over it?
