So appreciate your frank honesty with this. Watched my close friend go thru this for 3 yrs. Not pretty. Her strong faith was of a great help. Hoping same for you. Glad you have a cooperative sibling, as my friend did not have 1 out of 5. Option to exit life should ALREADY be in place. Our country head in the sand mode of operating is beyond sad, nearly criminal and certainly not humane. God bless, keep and strengthen you and give you rest.
