I've had that. It sucks, but it should pass. Do you play video games? I find thats a good destruction when it starts really getting on my nerves because it engages my mind and makes me focus, but in a way that I can still be scattered and looped. Might not be my best play through, but it's at least something distracting.

Likely this is part of hypomania and it's good to make some one you trust aware of it so that they can help you and keep you safe if you "go off the handle" for a bit. Or at least someone to tell you it's okay.

As for reading, take your time. You don't need to get everything.
