I work only 20 hours a week. It is a hard physical, but mostly brainless job. If it was a very thinking-oriented job, I could not last.
I have finally discovered that with depression and anxiety, working part-time is best for me. Full-time was excruciating and I can keep signs under control for a few hours a day.
I work because I don't want to be homeless.
I worked full time as a teacher for years following my diagnoses of depression and generalized anxiety disorder. I was also the mother of four kids so life was very busy and often stressful. I loved my job, though, and my medication was working. I also got lots of exercise even if I had to go out running at 10 pm or on my lunch break.
I work with depressiom days, however, I am not as productive, and, sometimes I have to take a sick day. Managing it with work is often difficult. Keep trying.
