The problem is, my "thoughts" (not to imply that I don't consider myself sentient, but to use the generic word for this particular phenomenon) don't really go away. That is, I can become completely miserable over something that happened 10 or 20 years ago (which is almost as far as my memory goes). I keep telling myself that nobody except myself even remembers that incident at this point, but it doesn't help... On the other hand, it only lasts a moment at a time, but in that moment I manage to become extremely upset. Time seems to play very little role. Such a weird thing.
