I usually get one of a few reactions from people, I either get laughed at, picked on or treated like I don't exist, if they're not just plain rude, I went through a phase where I was basically a functioning mute because what was the point of talking if no one bothered to listen or pretend to care, another thing I hate, is I'm supposed to go to social gatherings either for work, or family, and am missed when not there, but when I am I'm usually sitting in a corner alone because once again no one bothered to even notice I was present. So I just spend most of my time in my room, because apparently no one wants me around even though they pretend to miss me when I'm not there. No one has ever told me what I'm doing wrong either so I can fix things. Is this APD or something else?
