I used to cycle between moods daily at one stage, and as confusing and frustrating as it was, I would imagine it easier to hold down a job compared to being depressed or manic for months, bcoz you know the 'switch' is just around the corner... ... Idk how often I cycle now though, every 2 weeks or so? I could never do it personally (zero self-discipline) but agree that self-employment looks like a good choice for you from this angle.
