Following is the Diagnostic Criteria for Avoidant Personality Disorder:
1) avoids occupatioanal activities that have significant interpersonal contact because of fears of criticism, disapproval, or rejection.
(Given that you are a nurse, you obviously don't meet that criterion)
2) is unwilling to get involved with people unless certain of being liked
(I've seen you risk considerable disapproval by honestly stating your opinions on this forum, so you don't meet that criterion)
3) shows restraint within intimate relationshios because of the fear of being shamed or ridiculed
(I'd need more input from you on this one, but have seen nothing from you to date that would indicate that you would meet this criterion, either)
4) is preoccupied with being criticized or rejected in social situations
(Again, you would have to clarify, but the fact that you even started this thread would be an indication that this criterion does not hold true for you)
5) is inhibited in new interpersonal situations because of feelings of inadequacy
(You have given no indication of feelings of inadeqaucy in any situation, so again, I'm going to give this criterion a "no")
6) views self as socially inept, personally unappealing, or inferior to others
(A possible "yes" to the first qaulifier in this criterion)
7) is unusually reluctant to take personal risks ir to engage in new activities because they may prove embarrassing.
(the key here is "unusually" which means more than the normal amount of fear, and the "because". I'm going to give you a "no" on this one, too)
So, you possibly meet one of the criertia for Avoidant Personality Disorder. However, you would need to establish a pervasive pattern, and meet 4 or more of the criteria. So, you can relax. You don't have Avoidant Personality Disorder.:P
