So i was driving on the fwy, all of the sudden i was thinking negative like if something was going to happen, and it got to my head for some reason and all of the sudden my blood pressure drop i felt light headed & space out like i was losing strength, i started to breath & not trying to think negative & trying to relax because i got really scared to faint and crash I really wanted to pull over but didn't want the anxiety to beat me so i kept driving.. After 3 4 min pass i started feeling a little relax but i was a little shaky.. It was my first time, now im panic & scared that i can get another one while driving. :( what can i do?? Therapy? Has this happen to anyone? How did u overcome this?? Please!!! Advice!!! :)
