I used to write short stories in my early bipolar days. Depression would bring out the best stories, as I'd work out my own issues using the stock of characters I had. (Axe murdered my therapist once. Very therapeutic, (LOL) I think I might have been mad at her that week.)

As I've aged and stabilized the tenor of my writing has changed to children's stories. I do a lot of bedtime stories that I'm trying to turn into a sellable book, but with my winter depression being so bad, I haven't found the motivation to work on it. I figure spring will give me a better outlook as well as the non-depressed motivation to get working on it.

So, for me, it kind of works both ways. Depressed, I write and write, but don't produce anything I'd want a sane person to read. Stable, I can actually write good stories, based on the bed time stories I've been telling the kids for so long. Stable, my imagination is much wider and clearer and I'm pleased to show it to others.
