Do you write more or less during times when you’re depressed?   For me there are two kinds of depression, the kind that comes from failure or rejection (which usually leads to long sessions of writing), and the kind that comes from feeling worthless because I’m not writing enough (which is tougher to beat because it’s not intuitively obvious that the cause is not enough writing; breaking this sort of depression requires more willfulness, because the insidious thing is that is doesn’t particularly make me feel like writing; I just have to remind myself from past experience that productivity makes me feel not-worthless).
