Hello everyone! I thought I would post because although I don't have parcopresis myself I do have a similar affliction known as paruresis, and I think much of the same ideas apply. Finding other people with the same affliction was tremendously helpful to me, and I'd like to share a technique that I believe can be applied to any social phobia.

The method is called "paradoxical intention". The basic principle behind it is this: Ask yourself "What is my fear telling me to do?" Then proceed to turn around and do the exact opposite. If you are afraid of spending too long in the bathroom and people wondering "what's up?", then deliberately spend a long time in the bathroom (at least a good 15-20 minutes), whether you can poop or not. If you are afraid you will just be way too embarassed to tell your family/close friends, then tell them anyways and let yourself feel embarassed. If you've told your friends about your parcopresis and you're bothered by them constantly asking you whether you pooped or not, then TELL THEM that it bothers you! If you are afraid of people knowing you couldn't poop, then pretend to have a misfire. That is, deliberately go into the bathroom when you don't have to poop, and then tell your friends or whoever knows about your parcopresis that you had to poop but you just couldn't do it. Let yourself get used to telling people that you couldn't poop. There is absolutely no way for them to tell whether your really couldn't poop or you're just practicing paradoxical intention. Think about it. Parcopresis may be able to dictate whether you can poop or not, but you don't have to let it dictate how you react to it and what you believe about yourself because of it. It is NOT under your control and it is NOT YOUR FAULT!!! There is absolutely no reason to be ashamed of it. Get angry at parcopresis! If someone wants to think less of you because you have this problem, they can go to hell! Let your anger be your motivation. Aren't you fed up with what parcopresis is doing to your life?

I hope that helps. I will unashamedly admit that I did have problems with pooping and constipation throughout my childhood, and in fact a couple years ago I suffered a series of rectal fissures (ouch!) and ended up radically changing my diet and toilet habits to make sure it wouldn't happen again. Perhaps some of these would be helpful in fighting parcopresis, so I will list them here:

1) I now get at least 25 mg of fiber every single day, mostly from oatmeal and whole wheat bread. It took a couple weeks for my bowels to adjust, and I did get diarrhea a few times, but now I generally don't get diarrhea and every BM I have is soft and easy to pass.
2) I also drink more fluids (especially now since I'm working on overcoming paruresis). Fiber needs water in order to work properly.
3) I learned to stop straining. Pushing too hard was a bad habit I developed from being contipated and it was part of why I kept getting rectal tears even after I upped the fiber in my diet.
4) Pooping in the squatting position. For some reason I find it much easier to poop in the squatting position than while sitting. It may seem a little strange, but hey, you do what you have to! I have no problem with squatting and pooping onto a layer of toilet paper and then throwing it into the loo. I refuse to be ashamed of this! After all, it's only poop!

I'm also a commentator on poopreport.com, a website devoted to poop and pooping, and I am not ashamed of this either. I also appreciate that they have a Poop Health Knowledge Base (http://www.poopreport.com/Doctor/index.html), devoted to poop-related medical problems.

I wish you all the best of luck in your struggle. Everyone has their crap in life to deal with (no pun intended!).
