I am the same way, silent. But, mine shows as Avoidant Personality DIsorder. I avoid situations that would enable people to reject me. I have anxiety around situations where i have to face possible rejection or judgment like interviews, exams, etc. If I screw up or forget a small chore at work and my supervisor brings it up to me...I crash on myself for it. I feel extremely stupid, regardless if it was too darn busy to accomplish everything she wanted me to. Regardless if we were short staffed and half my work time had to be put into another person's job as well as my own. I should have been able to do everything AND the extra work load.

My own expectations are very high also.
