Hang in there and don't give up. I read in one of your posts that the SFS (I'm new, and hopefully got that acronym correct) is Metamucil. I've read on the boards -- in multiple places -- that Metamucil is not the best SFS. I take Citrucel (even though it scares me b/c I'm normally a D) and it helps me a lot. It is the only SFS I've ever taken that doesn't cause a lot of gas and bloating. Look on the boards b/c I think that others recommend Heather's Acacia as well.
I know that it's hard to not "obsess" about your tummy always hurting. Believe me, I spend way too much time thinking about it and analyzing what I'm doing wrong. We're all here to help each other. To some degree, I'm sure that we all have the same moments that you do where we want to "hibernate" in our rooms. In fact, I just felt that way last week and it was miserable. But I came through and and have been working hard to get back on track again.
Hang in there. . .things will get better. On the positive side please remember that you CARE enough about yourself and the way you're feeling to make things better. How could anyone fault themselves for being proactive in managing their health?
Take care and feel better. There will be better days ahead!
