anxiety update August 28

I just had a major panic attack. It lasted about 15 minutes. I get these once in a while, usually connected with a medication I took, such as prednisone or percocyt. This one was unique in that I didn't take anything recently that should cause one, although I did just take my daily dose of prednisone (10 mgs, small). I changed my fentynal patch yesterday and although I doubled the dose, I don't believe that was the cause. I am OK now, I think. I tried to take deep breaths and distract myself by watching television. For those of you who have never experienced a panic attack, it is quite a scary thing. Particularly, because rationally / intelectually I know nothing is wrong, but my body is in complete "fight or flight" mode. I hope that it has passed.
