I hope what I tell you will help. I am a mother and obviously also someone's child. As a mother, I don't want my child to throw his life away on me, no matter what, and I don't think you should sacrifice yours to your mother. Have your siblings really "given up on her" or have they done what I think is the right thing, and gone on to live their own lives? If your mother is the one who told you she was over-medicated, that is really between your mother and her doctor. My guess is she felt crummy when her body was trying to adjust to the medications and she quit before the doctor could even get a baseline of their effectiveness for her. Please try to see that your mother 'doesn't have a problem' because she has shoved all of the attending difficulties off onto you. If you really want to help your mother, try to get someone she respects (if possible) to help her find another doctor; then sit her down and tell her what you are willing to do to help her (I'd be willing to drive her to the doctor) and what you are not (pay her credit card bills when she goes on a spree, lie about the misery her behavior causes). You have my heart felt sympathy.
