I could have written your list of symptoms. I have been have generalized anxiety since October, pretty bad since December. I, too, quit my job. I took Lexapro for four days and it was poison to my system. Did Tranxene for three weeks, took myself off of that, tried BuSpar and it was also toxic for me. Just when I was resigned to living like this, I was diagnosed with adrenal fatigue. Changing my diet has made a tremendous difference for me. That all-day-long jittery feeling is gone. I will go to get testing done this week, also having allergy testing done. There is hope!
