On the list of things that people who are not majorly and openly mentally ill do not understand that they should not say to people who are, in fact, majorly and openly mentally ill: “Well, when you’re feeling like crap, it doesn’t help to just sit around.”
You know what? That is actually the problem. It doesn’t help to just sit around, no, but there are a million possible reasons why it isn’t going to help to get up and go do something, either. If I felt like today was one of the days when doing something would help, I would be out and about to shake this funk instead of calling you. As it is, will you please let me cancel our dinner plans in peace?
