I am so sorry about your mother's diagnosis. I know how painful it is to to watch your loved one fade away. My mom died 28 years ago and I still miss her every day. My husband just passed February 22 and I am numb with sorrow and loneliness. Enjoy your mom's good days and be supportive on her bad days. If there is nothing else, please get hospice. They will make her comfortable, take away any anxiety and restlessness or delirium that goes with passing from cancer. Ask for morhpine, haldol and atavan. She will be comfortable. She will hear what you say to her. Love her every day and let her know how much you love her. If the Lord does take her, take heart in knowing you will be reunited. That is how I get through my lonely days. God bless you and your family.
