I think we men are full of fear. Fear that comes in a variety of flavors.
Nick, you are a strong, extremely successful man. That's enough to deter most guys right there. What could we possibly offer that you couldn't supply yourself, and probably better than we could at our best? Who are we to offer insight? Perspective? Like it or not you are an alpha. To admit to ourselves that you require assistance . . . well, what does that mean for us? If you can be vulnerable, what chance have we?
Yes, I'm also convinced that we eventually turn any situation back on ourselves. That's not necessarily narcissistic. It's human. A survival trait.
There is also the fear, through our inability to 'fix' the situation for you, that we might make things worse.
There is the fear - a basic, primal, 'magical thinking' - that tells us that if we give voice and recognize the severity, the reality of what you are experiencing, that somehow we will also somehow be touched or bring illness into our lives.
There is the fear that if we talk, we will feel. And, among most men, feeling is weakness.
There is also the fear that we are interfering in an extremely personal time for all of you.
And we are afraid of a thousand other major and minor things that twist inside until all we can do is offer platitudes and change the subject.
