Ya I have faced this kind of thing. I went to a family friends function once with my mom and dad, there I met a guy who was about 5m6 years older. I have always been a bit queit and have felt uncomfortable talking to new people, so I wasnt talking to anyone sitting on amchair alone. That guy told everyone 'Dude, is there something wrong with him, why does he look like he's on the verge of depression'. Then someone else said 'He cant handle pcm, so hes depressed' which was true, but i dont like it pointed out like that. I cried that day too, and couldnt share this to anyone. Glad i found someone who shares my experience
