Why Am I So Bothered?

I dont know if its hormones, being sick, or what. I just feel "off". I know I'm irritable more than usual because of not feeling well. Maybe that's it.

*UPDATED* this morning :) I'm feeling a lot better about things, and vuah-lah, my cold/flu bug seems to be on the mend too. So yay. Hopefully it was all just a result of feeling yucky!
