Have you tried meditation to quiet your mind? I've never had quite what you're saying with that kind of inner dialog.. with me it's usually more similar to the first two.. I'll start getting down, then try to pull myself out of it.. then repeat.. or sometimes not repeat and just get down until I force myself out of it.

Best of luck. Stay strong!

p.s. If you have Netflix, a good movie to watch is 'The Life of Buddha'.. it's very inspirational!
