I skipped training because of that headache, despite my back being workable enough to go. That resulted in me lying in bed at 7:30pm, feeling and acting incredibly grumpy. I was not pleasant company last night. I was angry I wasn't at training, and frustrated with my writing yesterday, and it was not a good night.
Today is much better. My headache, which I think is related to my back issues, has faded into the background. I slept very well, also. That's helped my mood. Things are looking better today. I might go back and rewrite what I did yesterday. We'll see.
For now, though, I'm going to revel in not feeling miserable. Then I'm going to get to work. There's a story what needs writing.
