I agree with farm girl that it is my thinking that drives me over the edge. I have racing and looping thoughts. They are obsessive, driving force and at the same time I don't have just one thought. It's like spinning the dial on the radio, (like an old style radio, not a search function,) where as you pass the channels you don't stop on you can still hear the clips and snips of voices, and you just randomly stop on random chanels for long enough to catch 1-2 words then move on.

That's my thought process.
