Exhausted

So tired as of late.  I am teaching 23 hours a week and it is crazy.  I feel like I have no time to do anything.  I get home and I don't want to do anything.  It is pathetic.  Not saying it is super hard but at the same time bleh.  I barely have any class-prep time.  I feel like I am working more than I ever did as a sales-associate or anything.  Even when I had 8 hour days there.  Bleh. Bleh. Bleh.
