I am very much in the "take it one step and one day at a time" mind-set. :)

The diagnostic process has taken a ridiculous amount of time. Some of the delays would have been avoidable in an ideal world, and some have been unavoidable. We do the best we can; it's all we can ever do.

Sorry to hear about your back. I know what a blessing it is that I've never had serious back trouble, and I can only imagine how hard it makes it to get through a day. Hope it clears up quickly.
