Thinking Is not an option!

I am sat in front of my iPad trying to think of stories, but somethings gone missing, I've been robbed of my ideas. For years I have wanted to write children's books. I have stacks of ideas I've started, half written stories, scribbling and notes. 

But In these past few months I just can't think. I have no ideas. I have lost the excitement for it. I am surrounded by fatigue and a dizzy head. Thinking has left me.

Is it the drugs, the fibromyalgia, pain? Whatever it is, I need to get my thinking back. I want to write. I need a way to get focuses.
