I think you "diagnoses" of MLC could well be right. It was interesting to read about your separate life issues, it seems to be the exception rather than the rule! And I think it might support the MLC too! I think it is a rare MLCer that thinks they are going throught a MLC!
I don't have any nuggets of wisdom, keep posting, and you will attract people! If I think of anyone in particular, I'll point them this way!
