ugh

This morning at the pharmacy we managed to get caught up a little sooner than expected, so I was able to clock out early, allowing me around an hour to work on stuff before I need to head to campus.
Problem is, I'm at that point where that hour really needs to be three or four.  I feel really haunted by not being able to handle my stress level a week or so before.  I realize I'm sounding like a broken record and a pain in the (bleep) about this, but the chain reaction it's triggered is just staggering.  I feel so discouraged that I could actually be a beaten man right here, right now.
There is definitely part of me that says to fight on.  But a growing part of me wants to throw in the towel -- I don't even want to know how badly I bombed out (sorry for the word choice but that's all I can think of) my exam on Monday -- and I really don't care what the underlying excuse might be, because that's not a good sign.  Period.
