Years ago my mother made several hurtful comments, criticizing me for taking anti-depressants; my coworkers have made comments about how they wouldn't want to work with people with mental problems and how they wouldn't want to take psychotropic medications. I haven't told them I have depression or that I take medication for it. I do try to gently instruct them that people with mental health issues are people first, that they need compassion and that many of them do work and/or could work if they were in supportive environments. When I have heard jokes about suicide I've calmly said I didn't find such conversation amusing. Since many people don't really intend to be mean or cruel, I try to word my response so as not to embarrass them.
