I don't think there is such a thing as "normal". I think the best we can do is either functioning or non functioning. We amble through life confused. When I was a little boy I thought my mother had all of the answers. The day I figured out that she was guessing along with me was heart rending. I thought I'd come to an age where I'd 'get it'. That is the illusion. No one 'gets it.' We just do our best and forget the rest. There are those of us though who seem to be behind on the getting it bit. Such great facades and shrouds of who they truly are. We believe them because really even if we didn't we'd have no answers to their questions.
My sister is one of these people. I love her dearly. But there is nothing I can do for her... just love her. It seems at times that she feels that my family owes her some debt because we function more often than not while she missteps, faulters and fails in her own mind. I'm not sure what to do with her/for her. I watch her hurt herself and therby those around her namely her children. She clings to this religion and I think she needs it. Once after her second child was born she attempted suicide. I remember standing over her hospital bed, looking down at her. She opened her eyes and smiled. Such a beautiful woman once my hero, brought down to this. Slurred words, slow blink eyes and two little kids in the waiting room wanting to know what was wrong with mommy. For the life of me I never know what to tell them to this day when they ask me that. "Mommy is sick kids" The statement just has no teeth... and it has no cure either... just love the crazy people as much for them as for us. It's all the answer we've got.
