I am not sure of the objective measure of severity but I would personally say mine is very severe and intrusive. It is something that is recognised by everybody immediately upon meeting - like a black hole that sucks away every other aspect of myself from what people see when we interact. There are very few people in my life who have not been shaken by that initial awkwardness or discomfort and so can speak to me normally. I get treated as incredibly stupid and spoken to in a demeaning way by a lot of people. I don’t think that I imagine this but it is entirely possible that there is something within my control that would make people feel less unhappy to interact with me or less likely to judge me harshly. I do think that I am at fault, to some extent or another, because I no longer make any efforts to socialise, however, the endeavour is so often futile that I think my reluctance is more so a consequence of my position than my personally - I do believe most people would do the same but who knows?
