You need to get this person to go to a psychiatrist or a therapist. We, here, are not doctors and can NOT give you any kind of diagnosis. It definitely sounds like she needs some major help both physically and mentally but only her husband can help her get it if she doesn't admit to herself that there might be problems. You and Dad need to have a very serious talk about this so that you can make him see what you see. Show him what you wrote here if you think that would help. Maybe if he saw it in writing he would recognize her and see the problem. Good Luck to you.
