Hi Coko, Sorry to hear about your current crisis and as I immediately read your post I thought id reply as i am currently going thru exactly the same issues with panic attacks associated and exacebated by OCD! I have been experiencing very harsh heart beats and my breathing has been eratic,poor concentration and marathons of sleepless nites(3 days in a row so far).Ive been concentrating on my breathing as erratic as its been and have managed to eliviate some of the tension in particular in my chest region, in slowly working on it and I try to improve my posture when my breathing becomes erratic as well as isolating myself from external and environmental intersections so my mind doesnt become more cluttered with events..Although perhaps ones individual experience varies from person to person I hope you find some relief.Take care and hope issues and health improves for you. Bluzman!
