I'm not for telling people at work or your boss. I think you are treated really differently. I used to lie and say I had severe migraines or kidney problems. This shut people up and they didn't seem interested.

My friends and family and some neighbors know I suffer from depression. This is because I've had to cancel on them when I don't feel well. For some reason, people seem to understand depression, but bipolar scares them off.

This is just my experience, not saying anyone else should do this.
