I don't really fake that I'm "fine" but my honesty is variable. Some people don't need to know anything. Some people "can't handle the truth."

A lot of time, if I'm putting on an act, it's because I can't handle the interactions that would come from an honest representation of my mood. And like others have said, the world keeps turning and I have to get through the day one way or another and other people get worn out by someone who's always down (boy who cried wolf syndrome).

I'm also in an early career position and showing any signs of weakness is opening yourself up to scrutiny that could be problematic down the road. I have genuine concerns about my MI causing problems with work, but I don't think that should prevent me from trying.
