To think about the worst thing i could do at that moment?
Sometimes, when I'm in a delicate situation, or in a position in which the next things I say effect me, such as a job interview, I CONSTANTLY think abut the worst possible thing I could do or say at that moment.
Whats worse though, is that I sometimes physically react to what I think about, so if I imagine kicking a relatives child in the head, or saying something incredibly stupid to my manager, I'll audibly groan and sometimes even cringe right in front of the person.
Is it normal?
