Im fine with "formal" situations like shopping in a mall, buying clothes for myself, eating around others, getting my hair cut. Im completely fine with that, cos those are things i dont have to show the "real me" and therefore there can be no judgement, i can even ask for discounts at shops and return something ive bought to get my money back. These things are no problem for me. But im exceptional i guess.
But when the social interactions go to a "personal" level, when you have to be yourself , i get extremely anxious, blush , sweat and stuff. So i normally get nervous around people i know, rather than people i dont know. Thats why my doctor thinks mine is not SP, she says its an obsession about social interactions, she says im a perfectionist (which i am indeed), and when i see im not "good enough" for something (which is social interactions in my case) , i totally avoid it... All or nothing...
