I was impressed with your mature outlook and concern about your mother. It touched me.
If you can take some of the suggestions here and see if they apply or if you can use them to help you...especially if you can get to an al-anon or al-ateen meeting, you would find others who may be in the same situation. I hope you can learn how to deal with such a difficult problem and at the same time, take care of yourself. God Bless You Jordyne...(I have a daughter named Jordan--she is my rock.)
