Hi Fix,
Been wondering how you were doing.
I don't think you're crazy, but sane people can do crazy things, smart people can do dumb things, etc. I think most folks here can at least understand/relate to that. Stress... (e.g. pain) can certainly push us over the edge under extreme circumstances.
I am concerned when you say things like, "
I get to points when I am in soooo much pain that I seriously cannot focus on ANYTHING but pain." If that's venting (we all vent at times, and that's fine, especially here), that's cool.

But if pain is really taking over your life to the point that it consumes you and becomes incapacitating... that's
not so good.
The fact that you have "
more good days and less terrible ones" is a good thing and, IMO, something to keep in the forefront of your thinking and coping.
There are many ways of coping/dealing with chronic pain. Most of mine involve distraction (so I'm
not thinking about pain to the exclusion of all else), but mine don't work for everyone, and there are others. I've tried a lot/most of them, so I know firsthand that it can be a difficult process to find what works best for each of us.
