I do have a category in my mind of "Things I will think about in a bit but not right now." I talk about it as good, healthy denial. If there's something I'm having trouble handling or accepting, the procedure - and I'm fully conscious of this - goes "not happening not happening not happening not happening OMGSCARY ok, that's done now" over some lengthy period of time. It is strictly time limited, and I know it's going to terminate in some reasonable time, but it's a way to get to it when I'm good and ready.
