Yes, it's irrational thinking and logically I know that but I cannot control my breathing issues, my head feels like it will explode, my stomach eats itself. Logically I know it's an overreaction before I got really bad again I thought I had it all figured out and logically I could handle it. But the. It happened again and again and I had no control. I take a benzo if I have to be a passenger and plan to start driving more but I have a paranoia of the police for many reasons I cannot go into here. I don't want to get pulled over and be accused of something because I took a benzo a few hours before or something. It's so stressful and I believe it's PTSD related. mixed with nature. My mom thinks my babysitter might have been in a car accident and I do remember my dad was an aggressive driver......and he drove with a beer in his hand when I was a kid. Who knows why my phobia developed or why yours developed. I also almost drowned at the same time I developed the phobia and it was once suggested by an armchair phychiatrist it was connected and I do believe she is right. The logical mind can have you thinking normal but the body goes haywire then brain can be effected if it goes on too long. Bridges are very hard for me. Maybe because major ones collapsed where I live after Major Earthquakes in my area several years back. I think it was traumatizing for a lot of people. I believe I'm an HSP (hypersensitive person). I read a book and it talks about how about 10 percent or so of the population is very effected by stimuli in either direction. Made a lot of personal sense for me.
