My son took me because I was scared to go by myself She looks horrible.wieghs about 90lbs. I told her to go to the emergency. Room and tell them she's depressed.shes bipolar, alcoholic, meth addict and blames everyone else for her issues. What can I do? She begged me to bring her to my home I said no.she has burned bridges .but she's human and I want to get her help how can I do that without putting myself and my family in jeopardy?
