I'm not going to answer your original question, I don't think it's going to make you feel better.
q has stayed off prednisone by diligently using her meds and most importantly through very good luck...
To the OP, it sounds like you need a more proactive GI. You should not be tapering your prednisone so quickly if you're still having so many BMs per day that you can't leave the house. You're also on a pretty low dosage of Asacol. If I were you I would talk to your GI about
being more aggressive with your treatment -- a great way to start with very little risk of side effects would be adding rectal meds -- and also get into therapy.
edit: Just to clarify, not because therapy will cure your UC (it won't, and I really despise everyone who has ever told me I got sick because of 'emotional problems'), but because being diagnosed with a chronic illness is a really really hard thing to go through and even if you don't realize it yourself, you can definitely benefit from having a professional to talk to.
