Have you tried the rubber band around your wrist thing? I had some bad panic attacks in my early 20s and somebody told me to put a rubber band around my wrist and when an attack starts to come on, flick the band against your wrist repeatedly to induce pain. That was such a hazy period that I can't remember if it worked for me or not. I mean, it's probably doubtful, but then why would he say it worked for him? I don't know. I'm ranting at this point.
