I can take a hit. I've boxed professionally. I've kicked and wrestled with the best of them. In fact I've been punched, kicked, choked, cut, bitten, had my joints 'popped' and, on one occasion, even had my bones snapped in fights and, for the most part, I've been able to push through the pain and laugh if all off (the bone-snapping incident being somewhat of an exception).
Even so, I'm a tough guy, and yet there's one area of life where every blow I receive knocks me to the ground. It's the battle for my kids.
I've been divorced. The separation was not amicable. I struggled (initially) to get access to my daughter. And yes, I contemplated suicide ... regularly.
If you're a bloke who's been through this sort of thing, you know exactly what I am talking about.
