Hi, I want to help my sister who lives in california I live in Illinois. She is 34 and previously has done drugs in the last 3 years, she has also had a very adorable baby who is now two and a half. She is withdrawn, out of the blue violent at times and sleeps large portions of the day. She does not leave the house. She stays with my father who this year lost both parents and he can not deal with her so he works all the time. My fear is for my neice and of course my sister. She refuses to go to the doctor. And at her age my father says he cant make her go. I plan to fly there in the next couple weeks. What can I do? What can be suggested?
