You know Mike, there are a ton of books out there to help women face personal and family issues but far too few for men. Society all to often brands men to be the stereotypical macho, football lovin, beer drinking, strong man who goes out kills the animal and brings it home to skin it, grill it and cook it so to speak. Truth is where our families are concerned we face allot of fears, especially where something like what you have gone through is concerned. But men in general don't know how to deal with it and feel emotionally like an island to them self.
The lessons, the "survival skills" and even the trust in a power higher than yourself were given to you for a reason greater than just your own personal needs. I have a feeling there are allot of men married with families or even single that need to hear and read what you have to say. It's hard to imagine on a deeper level but the pain, difficulties, trials and tragedies we suffer are either a gift full of lessons to strengthen us and teach others or something that will immobilize us and slowly destroy us from the inside out. Seems to me which one it becomes is ours for the choosing. You have chosen the gift. So just go for it. Let those lessons flow from your being into book form. And as you know already you have allot of support out here.
