Avoidant Personality Disorder deals with many other means of judgment, not just ssocial interaction. My anxieties also include assessments, interviews, exams, etc. It does not have to be direct contact with people. Any situation that indicates dissatisfaction of me or my performance is a stressor. It could be a written paper being graded. I avoid situations that lead to judgment or if I cannot avoid it, I get very anxious and have anxiety attacks.

A neighbour once reported me to Children's Services for not keeping my knives in a locked drawer. I have done many public speaking engagements without stress, but when it came to being graded in university, I had to take ativan. A coworker was having a bad few days and would not speak to me during shifts. This was a huge trigger for me because it indicated to me that I had done something wrong. I couldn't avoid the situation and rejection or silence and had a major anxiety attack.

Social Anxiety is more specific. It deals specifically with people. Avoidance takes on other scenarios.
