Hi. I am 21 and have Panic Attacks whilst driving. It mainly occurs at nighttime. I feel like everything is tight and i'm almost fighting for breath and to keep my heart from racing too much. I cannot stop it. My doctor put me on beta blockers, i've been on them for months and they don't seem to help. I don't travel in a car much anymore, and I would love to be able to again. What can I do? I've tried driving more to fight it but it never works. It's uncontrollable - could it be hormonal, due to a higher stress situation and my body cannot cope? I am not depressed at all. Please help.
