Junior, after reading your post I felt I should respond. Yes, yes, it is possible to remain in an anxiety attack for a long time. Last tuesday I was curled up in a fetal postion on the livingroom floor for 8 hours. I wouldn't move for fear. I felt so fragile in my chest area that I thought if I moved I would surely die. The panic attack would come, peak, subside and then come again, Over and over. My kids walked around me scared and upset. That was one of my worst days. The really bad cycle with intense attacks seems to last a couple of weeks for me. I have been suffering steady for about a month now (and off and on since August). This Sunday I noticed a change. Yesterday was not great (but not nearly severe as before) and today was much much better. Only one small episode in the grocery store. I had a severe cycle of panic about 11 years ago for 3 months and then just once in awhile over the years until this past August when I freaked out after taking Ibiprophen. I got all light headed and tightness on my left side, with waves of anxiety coming over and over for 2 hours. I thought it was a reaction to the pain killer at the time, but now I realize I have a phobia about meds. I wish you well, and pray that God will help you through this. I have experienced His nearness to me and have called out to Him for help many many times!
