Exhaustion

I am completely exhausted. I feel like I run around constantly for twelve hours every day, and I never quite get the breather (or the sleep) that I need.
Today we had a crazy mail day. We're talking like, 6-8 carts of mail. Three of them were UPS. So I worked over three hours, Buffy worked who knows how long, and we had three desk attendants helping throughout the day. However, one hurt more than helped when they tagged all the UPS as regular mail and we had to go through and re-record them and figure out how to let the desk attendants know which ones needed to be signed for.
Other than that, I had O-chem recitation today for the first time. At one point my TA asked if anyone hadn't taken 105/106. I was the only one that raised my hand. And so he asked me to talk to him after class because the first test is all 105/106 based. So after class I went up to him and when he found out that I'd taken 105 and just not 106, his response was, "well, then you should be fine... for now". He said that he'd be really honest with us, and if we asked him if we should drop the class and if he thought we should he'd tell us straight up. Exactly the reason that I don't want to ask. I can do this. I can do this.
In Welsh tonight my instructor told me that I had a guaranteed in for the study abroad because I had taken the Welsh classes. And the payment schedule seems do-able, so hopefully...
Well, I'm literally exhausted. As in already falling asleep in classes exhausted. So I'm off to do some homework, and then I'm sleeping. For a long time.
