Krissie
You and me are kind of in the same spot my Dad is dieing from his diabetes and there is nothing I can do about it, but be there by phone since he lives in the lower 48 I know that he only has a few more months to live but every call means more to him knowing that I care for him dearly
I'm sorry that you too are having to deal with this to but your Mother know deep down in her heart that you love her so, and knows you need to heal and can't allways be by her side but every call or visit you do means a lot more then you think to her.
Take care Krissie, I'm alway's there for you girl
