Actually, you're not the only one to suffer mood swings like this! Personally, I've been on a downer for a week or so (although that could be my cold, plus the undecorated state of our house, or something.....) but often find myself feeling angry, for no reason at all.

Unfortunately, when I get tired/angry/frustrated/depressed? Writing is the very last, ultimate thing I ever feel like doing. That's why my LJ has gone horribly quiet.
