Frustration

So I'm standing here in the middle of the lab, hurling an eraser around the room off the ceiling and the walls because I don't have my sabre with me and I don't know what else to do.

I don't know what to do.

I don't know how to undo the damage that I have done.
I don't know whether I should; I don't know if I'm doing the right thing. I don't know if I manage to start where I'll wind up, or whether I'll just go crackers again.

I don't know whether I'm hurting alone.

I don't know why I'm bouncing this stupid eraser off the walls, it isn't really making me feel any better.

And now I don't know where the eraser's gone.
