UGH! I hate that feeling. Unfortunately I think it comes w/ the territory. You'll have a "good peak" soon, it's just a waiting game. In the mean time try some rational thinking ... I've been told many times "how many times have you thought you'd be sick? ... uh huh ... and how many times has it happened?" I know it sounds real simple and I actually am trying to use that one on myself lol but it's worth a shot.
