I've also read that the typical panic profile is a perfectionist which totally fits me! And also the fear of shame. That is why we all rush to the washroom and are suddenly "okay" because there is no longer the risk of public 'disgrace.'
I have done SO much reading on this, I could go on and on. I felt very isolated when it first started for me in the eighties and there was no internet support and even the doctor didn't know quite what to do with me. "Feel the Fear and do it anyway" (by Dr. Susan Jeffers) is a great book that really helped me. Even now I sometimes struggle with being away from home during holidays etc.
