Being lost doesn't hurt. Being lonely does. Loneliness is typically known as the worst kind of suffering. I am lonely. I've lost a lot of friends, and broadly speaking, my fifth-grade best friend is the one that hurt the most. We would be getting in trouble together; we even got suspended together...However, losing her left me lost. Part of me wishes I could go back and keep her forever, but I cannot, at least by human means.
