I haven't told people other than family members. But my diagnosis is just clinical depression so I don't think I'd suffer from a stigma anyway.
I think it's unfortunate that people think the way they do about mental illness. Their mindset it still in the dark ages, i.e. "snake pits" of mental hospitals and people being chained to walls.

It's certainly nowhere NEAR that way anymore!
I guess it's going to take forever for them to change their way of thinking.
