I can see you are hurting and there is a lot of raw emotion. You are further in the grieving cycle than he is, and you have to remember you most likely always will be. From being in such a low place true personnel growth can occur. Use this all as your motivation for GAL. Take care of yourself so you can take care of your S.

I am fairly certain that is the understanding that with hope and hard work all things are possible.
