The curse of knowing too much

Man you just can't fucking enjoy or live a moment peacefully there's this constant awareness about everything,this won't last for long, u won't live any moment like this again, all of this will become a memory once. I srsly can't live in the present either I'm living in the nostalgia of my past or visualizing my future, but i srsly can't really in my present. How do i really get rid of having 100 thoughts per minute man???
