Having recently been suffering from this I know how horrible and dehabiliting it can be. With me I also get chest discomfort and arm tingling which makes me think I'm having a heart attack which obviously makes me worse too.
The best thing I can say is that you just have to tell yourself that absolutely NOTHING bad is going to happen, it's anxiety, it's harmless. The feelings of panic and dread WILL pass. Valairum Root capsules from Holland and Barrett are supposed to be quite good and you can also get rescue remedy sweets from Boots that you suck on and have four drops of rescue remedy in per sweet.
Chin up Jack - you ain't alone with this. Don't let it beat you
