Once again I find myself unable to sleep and knowing that I must get some sleep in order to fullfill my promised obligations for today.

I hate being the way that I am because if I know I am expected to do something I find that I cannot sleep the night before. Its like I am sliding down a slippery slop toward an abyss and there is nothing I can do to stop my decent.
"Hey Will I need you to help me tomorrow clean up my place. I just got rid of those red neck renters who trashed the place." From that point on my day has been frelled. I cannot say no, so I am obligated to help.

I owe them to much to say no, and I am paying the price now by not being able to sleep.
Do any of you suffor from this afflictions?
