I completely relate to this. During my last breakdown at the beginning of this year I made some terribly stupid decisions that had some dire consequences. It really damaged my confidence and I've struggled with day-to-day decision making which used to be very easy for me.

Well, there are levels of psychosis. I've never completely lost touch with reality, but I've had delusions which were strong enough for me to act on. I've seen other people have full psychotic breaks in real life three times now, and really view it as a continuum.
