Us kids didn't want to go see our maternal grandparents either. Once, my father got so pissed at me for refusing to load up, he picked me up and threw me against the wall.
I know it sounds terrible, but I landed on my bed and he re-ruptured himself, having just had hernia surgery!!!

Hope you're not making your kids go. Hope you're not making yourself go. But, that's just me. Maybe you could ease yerself into the no show concept by doing somethng else: like help at a soup kitchen???? or something else that is good for your self esteem and your goodness is appreciated.....
