How do you relax / turn off?

I was wondering how other INFJs deal with their constant "thinking". I honestly exhaust myself, because my brain doesn't take breaks from dealing with issues: whether it's work, household chores, relationships, politics, economics, or other ways to save the world. My head is constantly churning over problems and how to fix them, or on a particularly bad day, I'll just have arguments with real or fictional people in my head. And it just never stops, which is particularly frustrating when you are trying to go to sleep.

One of my coping mechanisms that I've recently started to adopt is to stop myself and think about fictional stories instead. Fantasy worlds with fantasy characters, simply keeping my mind busy by making up fun stories.

Another alternative is watching a movie or a series, of course. As long as it's engaging enough it definitely keeps my mind from wandering, but it's obviously not always possible, especially when out and about.

Anyone else out there who can relate to this problem? What do you guys do, when in need for some relaxation?
