There's a very scary moment when you realize that what you think you are currently living actually ended a while ago, maybe 3 days ago. You realize that you won't stop replaying things in your head because you're afraid of losing the memory. As long as you keep it playing on an endless loop, you keep it alive. You are trying to cheat memory and time.
Come to think of it, it is in fact your call. You are welcome to try whatever you'd like. No one's coming up to you to tell you to stop. The problem is, you'll fail. You're welcome to try. But you'll fail. Because trying to keep a memory alive is like the Heisenberg principle. The more you try to remember it by replaying it over and over again, the more you morph what it actually was, until you've lost what you wanted anyway. And you're just tired from trying.
