Reading the scariest memoir I've ever read

I have a headache right now.

In fact, I get headaches pretty frequently.

But what if THE HEADACHE NEVER EVER EVER EVER WENT AWAY?!?!?!?!

That is the book I'm reading right now. It's All In My Head, and it's about a woman who gets a headache and goes to doctor after doctor, but the headache doesn't ever go away. And it is the scariest thing I've ever read.
