I'm glad to hear you got a result with your GP, Mike. I had a girlfriend a few years back that started suffering from panic attacks. At one stage it got so bad that she wouldn't leave the house without me. Her GP was dismissive and simply wrote out a prescription for anti-depressants. There didn't seem to be a lot of information out there at the time, but we read what was available and she tackled the problem herself with support from me. We're still friends and, six years on, she hasn't had any recurrences.
