I'm sorry to have been so cranky. Most of it is, there's this big scary extraction I have to do on the soil, and I'm worrying about it - when I'll find time to do it, if we have the necessary chemicals and equipment, if I can do it without screwing it up royally or hurting myself in the process (Chemistry and I have a bad past).

The worst part is, I have visions of myself in the lab a 2:30 am, still working on the d_______d extractions, because everything chemistry takes twice as long for me as it should.

This afternoon, though, I have to focus on writing an exam and preparing Final Exam Topics To Review sheets for my classes. I am telling myself I don't have to worry about the Big Scary Extraction until next week, but that doesn't help much.
