Bad Mood

I'm in a pretty bad mood. I thought it might be low blood sugar but I am still feeling cranky after lunch. It could be from the pain. Inflammation in my muscles from the big hike is subsiding but now my knee HURTS. I took a couple of ibuprofen which had a nice placebo effect, if nothing else. Or it could be because I wanted to give my notice but my boss disappeared for a meeting. Or, maybe it is the T though the last time my bad mood was near the end of my cycle, not the beginning. Or maybe it is just a regular old bad mood that has no rhyme or reason.
