My complete condolensces go out to you and your family. When someone is missing, I cannot begin to imagine what it feels like, at least when a relative passes away, we know what happened and why, etc. I will post links for you Diane. That is a very sad story...
I relate to it, in a way, (and in a small way) cuz I am for the third time trying to have a relationship with my father (i am 30 , he is almost 60), I understand some of the feelings you expressed. If there is any way I can help you let me know. My email is above.
