Laughter is the best stress-reliever. You should try it sometime and no,I'm not being mean or unsupportive. Try it. People could do much worse than call you quiet, and... You are admittidly quiet. So nobody concocted/spread vicious rumours. People poke fun and laugh at eachother, its called humour...Sorry you felt slighted in class, but here's a golden opportunity to work on yourself, you're gonna need a much thicker skin to get by in the working world, with sick miserable patients no less... Good luck.
