It's doable.

I used to have a high-stress job and it triggered lots of mixed episodes, which were followed by depression. (I'm rapid cycling.) I had to work from 8am until 7pm, and driving took me 1 hour each way due to rush hour. It was too much.

Now I have a low-stress job and no episodes have been triggered. So, I think the key to maintaining stability is to find as low stress of a job as possible. For example, a secretary job is low stress compared to a job in the food industry.

Usually the slower the pace, the less stressful it'll be. And the more "routine" your job is, the better off you'll be. (i.e., working the same hours and same days every week)

What kinds of jobs have you held in the past?
