Oh, self-employment & depression! It was swings and roundabouts, really. Good points were being able to choose when to work, and getting obsessively lost in it as distraction - probably not best for mental health, but very productive results-wise. Downsides were lacking confidence to win new business, being pissed off with clients' dumb questions, and not having the energy to say No. That last one could blight any self-employed person, though, I think.
If/when I get better, I'd rather work for myself than a company. A side effect of all this therapy is that I've got too much bloody insight in some ways: I find it hard to keep my mouth shut when people are wittering on dysfunctionally 
and am even more liable to come out with uncomfortable truths than I was before!
I'd probably make a good bar tender, mind you. Everyone could tell me their problems
