On Friday night, I went to bed at half 10, because my head hurt.
I woke up on Saturday feeling almost as fresh as a daisy - as fresh as a person with chronic pain and muscle tension can feel. My head felt fine, better than fine - it felt great.
Until it didn't.
It was about 11am, I think, when it started hurting. I still managed to tidy the garage up.
And it got to 3pm when I decided to have a nap, hoping I could sleep it away.
When I got up at 6pm, I felt better.
Until I didn't, again.
It's on these days when you feel there is no hope. When you feel as though you are going through a constant cycle, on a rollercoaster, through continual ups and downs. A ride you're not enjoying, but you can't get off.
It grinds you down in the end. It grinds you down and wears you out and you become exhausted.
Even though in the morning I felt really pretty good, last night it didn't seem like there would ever be anything different. Like my life would never be anything but pain.
And I started to think: this is my brain causing this. This pain may not just reside in my head - it may spread to my neck and shoulders and down my back and into my hips, but it starts there. And the brain is the nerve centre for the body, telling it what to do, keeping it functioning.
And mine seems to be damaged.
I am damaged.
Probably irreparably.
And I'm supposed to come to terms with that?
