I get these feelings also. I'm terrified of driving in cars. Im certain I'm going to die in a car wreck. I've been sure of this since childhood.

I believe what we are dealing with, are delusions. It sounds like this is causing a pretty serious amount of stress for you right now and it's best to talk to your doctor about what you are feeling.

I'm very sorry you are going through this right now. I hope you find someway to feel better soon. The only thing which helps me go on car trips, are benzo's. I wish that weren't the case, but it's the only thing to really help so far.
