I got into bed last night, lay down and within a few minutes I was clawing my way out of bed. I launched into a full-scale attack, almost passing out from hyperventilating. My husband (who "can't stand" this sort of thing), spoke me through it and got me breathing again but I was crying hysterically all the while.
I don't know what brought it on but I feel awful today. My whole body aches, as though I have been steam rollered.
This hasn't happened to me for many months - I hope it won't again!
