I have had Panic Attacks forever in a car as a passenger on motor ways / Dual Carriage ways / Night. I always take Diazepam 2 or 4 mg before I get in to a car but I don't want to use Diazepam anymore. I can deal with small terrors now but the big ones I can't my mind drifts away to thinking I'm going to die and there is no way out because I'm on a motor way I feel trapped. The big ones start when my muscles in my chest get tight and I feel like I can't get in air chocking I have never fainted in my life and I'm so scared of fainting its Scary so what am I asking is Has any one else had this problem? and what the hell can I do to help my self? I can't go on not getting in a car as a passenger.
