Most of us are in denial. We hide from the truth because if we know, we may feel that we have to do something.
In my case, i know that the little i can do, and the little bit i do, doesn't even scratch the surface. So, whenever possible, i select one to do it all for. It is still very little, but it seems like more, to that one person; and to me. A tiny smidgen of salve on a great gaping wound, but it is all I can manage.
