Concentration at Bay

I am unable to concentrate today. I just feel so on edge and at the same time, tired. I have way too much responsibility in my life. I take graduate classes full time, teach an undergrad class within working 20 hours for the office, and do 17 hours of field internship. It is just too much sometimes. I am running out of steam. And this is the last big push. I have 3 papers due. The hardest one is due in one week. One whole week. I haven't really started on it and what am I doing now? I am blogging about how I cant work instead of working. Ouch. It happens.
