anxiety
"I am 64 and earlier in my life i never had any gad/panic attacks. Not scared of anything! Then my first panic attack. I was on a freeway far from home and alone. Out of the blue..the clamminess, heart rate through the roof, shakes etc. I pulled off the freeway to a parking lot. I got out and my knees buckled. I was terrified. It finally subsided somewhat and i finished the trip on back highways.  . Now my trigger is driving even though all my life i loved driving anywhere..long distances alone..no problem until this. When i got home (barely) my dr. recommended .5 mg xanax as needed. A miracle drug for me! It makes me feel normal! I do not take every day"
