Hah that's interesting almost the exact same thing happens to me if I allow myself desired rather than scheduled sleep.
In a way though I wish my natural cycle was closer to the typical 9-5. I found it easy to be isolated or depressed on the days when your waking life is so different than everyone elses.
I've found it somewhat easy to feel very isolated in the same way. A week of freelance work at hours when pretty much the whole of the country is asleep takes some getting used to.
I recommend finding some Discord or IRC servers with like-minded individuals that may operate in other timezones, if that interests you. It's always the middle of the day somewhere, and I find that just having that communication available—even if I'm not looking at it or using it—really helps me feel connected and not so isolated.
All of these comments have been extremely interesting to me. Before this, I'd never spoken to anybody that shared my sleep pattern, so I had no way to gauge how uncommon it is.
