Back to full time

I have now had one week of being back up to full time and have started my second week. I am really tired because I have had class until 11 PM on Mondays and Wednesdays plus homework and papers to do. Sunday nite I didn't get much sleep because I had to get up early Monday to get a test done. So yesterday, Monday, I was yawning all day, stayed later to make up for the time I missed for the test and then went to class. Fortunately we got out early but I wasn't able to go to sleep early. Today I overslept which meant I had to stay at work later again. So the second week of back up to full time has gotten off to a rough start. Rougher still because on the way home I could not remember if I sent out the last fax that I had to do. Too tired I think. So I worried about that for a little while then I decided to call my office number and leave myself a message to check on it in the morning. That way if I forget about it by tomorrow morning there'll be a reminder waiting for me.
Anyway I have the feeling at the moment that I have no major responsibilities for projects, nothing shows up on the Master Project Record (MPR), just backing up people. Well whatever I say, but I feel a little off about that.
