A lot of bummer answers here and they are many feelings I have had, but now I am old, and I look at it like this. I once didn’t exist. One day, I will again not exist and I’ll never exist again. In the meantime, I get a very brief glimpse to open my eyes and see the universe. In it is a lot of things. Among them love, mac and cheese, peanut butter, sex, and dancing. A hearty laugh and a warm hug is worth all the pain it comes with.
