I recently wrote a story in which a psychiatrist was cursed into experiencing a major depression for a day by a witch patient. You can imagine who in my life might have inspired that.

It's hard for me to say if I feel less creative off or on meds. I know that my (subjective) level of creativity is generally linked to where I am in the mood cycle. Hypomanic, I will spontaneously compose annoying little songs about anything. Depressed, I feel too useless to do much of anything. Though I did complete a NaNoWriMo novel while depressed one year, so there are always exceptions.
