Melinda,
I'm so sorry that you have to deal with all this pain. I totally could relate to what your feeling, when they told my Dad there was nothing left to do the expression on his face will haunt me forever. Today is 9mts since my Dad passed and I think about that horrible day all the time. But I do find comfort in the fact that I told him how much I LOVED him every chance I got. so please let your Mom know how much you love her and that everything is going to be OK. The tears are just rolling down my face so please excuse any typos..
(((HUGS)))
Love, Michele
