My heart goes out to you. I hope you don't fall into a hole of depression and obsession and misery. Do you find that you're going a little stir-crazy? Are you getting the sense of "cabin fever?" Anxiety is the worst for IBS. Are you taking an anti-depressant or anything for your anxiety?
Re: the frequent bm issue
Mentally, I am very anal retentive, but physically I am everything but--butt--that. Is there some hobbie, exercise, craft, course you are up to taking? A distraction from IBS issues? It really sounds like you need to get "out," i.e. do something you designate as fun. Back to the frequent unloading and D streaks, though after that aside. It's like training a dog with oneself, a dog who's gut has been "insulted." It's like there's a reptilian memory or consciousness being activated. I know this sounds bizarre, however...it's so PRIMALLY rooted or seated.
