:ghug3 for you..
One of the hardest things to deal with is the hot and cold, the push me pull me. It leaves you unstable. It is like standing on a rug and never knowing when it is going to be pulled from under you. Even when it isn't being tugged away you wait anticipating the next wrench. The only way, I've found, to stop that is get off the rug and onto some more solid ground.
I wish you all the best for your recovery.. x
