I'm not often bored, though I have been having immense trouble in concentrating on things for months now. Sometimes I get restless so I can't keep still, though that's also difficult as my mobility is very restricted (I have arthritis).
To keep my mind off things I don't want to think about I tend to watch TV and play games like Solitaire or 2048, I can't usually concentrate enough to read a book.
If you are having a lot of physical pain, I take it that you have had physical causes ruled out?
Hope you find a solution soon.
