Getting concerned..

My anxiety is getting worse as the pregnancy progresses. I've always had it, and I've always been pretty good at managing (with the help of the hubby) 
I have mentioned it to my doctor, she said to let her know when I think it's going overboard so we can try and manage it. (I told her I don't want to be medicated unless absolutely necessary)
Here in the last week or so, I've noticed it getting worse while driving. I start thinking about me getting in a car accident and I can see my self standing back watching my car crash. It's pretty scary and I feel my chest tighten when it happens) When I get out of the car, I'm fine. I said something to my husband last night and started crying and he didn't seem to act as concerned as I am. 
Am I going crazy? Or is this hormones? 😕
