I made some extremely stupid decisions that day, but I am not normally a stupid person. I posted the story because it is a real life example of how having an IMCr can seduce you into a dangerous spiral of ever-more irrational decision making. Without in any way seeking to condone what I did, the additional pressures of flying single-pilot IFR in a typical club rental aircraft are not conducive to clarity of thought when the difficult choices have to be made.
