Does this count?
If not, then it's my circle of depression you wanted to know about. Basically, it goes like this: my health is going downhill because I don't take care of myself properly ---> to feel better and be healthier, I need to eat better and get good sleep ---> I try to do this for a week or two, but then I end up depressed again and stop caring, so therefore, I do not eat healthier or sleep well ---> End result: the tooth aches, the high blood pressure, and all the other BS I experience just comes back and I become more depressed, thus, the circle begins again.
