Hi,
I'm thinking along the same lines as Bizi.
This sounds like heightened energy and maybe some anxiety.
Do you think it is part of a mania?

Owww. Sorry about the stress fracture. Is there another kind of exercise you can practice for a while that takes the stress off the legs?
Swimming? Chair aerobics?
Yeah, I know that these don't have the same satisfaction that running has. My brain is dull.
