JSE,
I know its so hard ! to take your mind from the grim. i will tell myself "you wont be a victim to this darn uc" and the next thing i know i am in a paranoid state afaird to leave the house fearing an accident and i'm crying over anything and everything feeling helpless. Its demanding being sick as as important as it is to be positive , giving yourself a break and having a good cry , watch a funny movie , scream , buy yourself a cushiony toilet seat :) have a funny magazine to read while you sit and butt-heave( btw i call it dryheaving of the butt too! ha!)
it sucks when you have an ok -ish day then BAM next day hope is lost agian, but you'll feel better
ps
since i started being less active i will do some exercise on the treadmill/elipitical at home even if i have to force myself it does help !
i take those vitamins no problems
