You are seeing a sub-section of people during a fraction of the week and a fraction of the day. My non-mental health doctors and many other people I've told would never have guessed I had severe depression. I just don't present that way. I actually don't go long periods being stable. I'd say some of the people you're seeing may not be stable enough to hold jobs regardless of how they present. As for the others, I don't understand. I am a CPA and would very much like to get back to work. My pdoc says not at this time.
