I've noticed that there are certain songs, movies, memories, etc that make me sad. There is even a category of music we call "sad songs". It seems obvious that we would never listen to something that makes us sad. And yet I do, and so do many others.
Why is that? Why do we intentionally make ourselves sad sometimes?
Is it possible to overdose on it, and wind up getting ourselves into a loop of sorts? The song, for instance, makes us so sad and yet it feels so good that we play it again and again. The resulting funk is awfully hard to pull out of.
Sometimes people feel trapped by their circumstances. They roll thoughts around in their head of things that could change (but won't) that would make it better. This too is a painful, fruitless exercise. But I do it, and I know others do, too.
So what's up with that? Why do we do this?
