(((HUGS))) I hope you feel better soon.
I'm sorry about the headache, I also woke up with one today. Not fun. I hope you feel better soon!
I hope the rest of your day went better.
I often awake with some (often pointless or meaningless) phrase repeating itself incessantly until I sit down at the keyboard & exorcise it. Rarely a headache-provocation, though. Feel better soon.
The imbalance of thoughts outweighing actions can cause headaches. I sympathise. Been there.
ouch! May that headache go away quickly!
