lol. I know! 
I think Aparigraha (Non-Grasping) aspect of the 8-arms yoga field helped me overcome that, at least to a noticeable degree.
Belief sure is very important. I think some fields may not work if one lacks belief… although I’ve had experiences where automated workout field effects took place even when I didn’t know what was playing at the time.
Maybe try the For the Skeptics @Energetic Alchemy when you’re feeling really low and see what happens.
IMO, the best way to clear blockages / false beliefs is to debunk them by direct experience.
