Dear Sleep,
We where once so good together, I'm sorry our relationship has degraded to this level. To me it seemed that we where so good together but I see now it was really just that you where always there for me and I took that for granted. I'm sorry now that I always assumed that I could find my way back to you that you would always be waiting for me. I hope someday not too long from now if I try to be more dependable and have a less chaotic schedule you'll forgive me and we might be friends again. I know 8 hours out of 24 is a lot to ask, we can work back up to it slowly.
With love I sleeplessly await you.
p.s.
... hopefully it wont be a problem if you find someone else in the bed, I swear they're only a friend.
