I have had a moderate level of parcopresis, along with a severe parureis, for over 50 years. It started to be a problem before the age of 10.
Being bullied in public school and elsewhere made me very fearful and I felt I had to hold my bowels and urine all day long until I got home. But even then
I had a measure of problems.
Going into the Army, attending schools away from home made matters worst. I got panic attacks, and while in schools, left before the terms were over.
Bouts of depression resulted in poor decision-making in vital areas of my life.
It wasn't until I recently contacted the IPA and attended its workshop in Baltimore, Maryland that a significant change has been made in my paruresis. But I still need to tackle my parcopresis, even if it's at a somewhat manageable level.

Is there any way to get something going in the United States, particularly in
New Jersey?
