Anyone suffers from intrusive thoughts?

These thoughts been happening since I had 3 car accidents back in 2016. due to my anxiety and panic attacks I can't no longer drive because of the flashbacks I get which are horrible. but I hate it when I get these unwelcome thoughts, everytime I get in a vehicle and I'm just sitting there not talking or anything fighting off my anxiety. these thoughts starts kicking in, like if we at a traffic light and it turns green I'm always looking at the sides and thinking like what if we take off right now and a car runs the red light and hit us etc. thoughts like these and idk.. I haven't been diagnose just yet other than anxiety so idk if it's PTSD anyone else get like this as well?
