I have a few things I do as routines. For ex. I take my meds with breakfast and dinner. BUT I don't eat the same time every day! Breakfast: between 5:30 a.m. and 11:00 a.m. depending on my sleep schedule. Dinner between 5:00 p.m. and 8:30 p.m. depending on whether I go out in the evening or not. When I was a piano teacher, I made my own schedule, and kept to it depending on whether I had a huge depression crash or not. When depression hit, I'd call my mother and she'd call all my students for that day and say I was sick, which I was. That was before I had a dx or any meds. One of the reasons I could not work in The Great American [dysfunctional] Workplace was b/c of routines. Another was the workplace politics, and also being ordered to do things that were unethical, which I refused to do.
