Jimbo,
I am so sorry for your sadness and pain. I am glad that you are there for her, tho. It must be a great comfort to her.
Hang in there. I can only imagine your sorrow, but I hear in your words a very compassionate man, who is doing the best for him mom. God bless your Mom, your family and you. Remember that we are all here for you.
I lost my mom to alcohol related illness. She lost a kidney, ruined her heart, and had quit drinking, but the damage was done in her case. It is hard, but at least you know that you have done your best by her, and she is blessed to have you.
big hug,
chicory
