Oh, that is 100% me. I have this anxiety related to external (non-co-workers) people. When I know it's a negative response email, it makes my heart and body tense up. I know it's purely an internal response, a personal perception/projection, giving imaginative power away, etc etc. I try to woo-sa (meditate) through it, but it's still very real for me.

Side note, for a throwaway account - you are impressively dedicated to it.
