I need my wife out of our home?

Im filing for a divorce. As of the other day I have full custody of our child. My wife is a drug addict and is pretty much insane. I belive she suffers from mental illness beyond her control, but will not make any steps to get healthy other than wanting more drugs from her doctors. They will not give her what she wants as they know she's addicted to drugs. I feel bad for her as her entire family has shut her out and no one will take her in. I tried to get her healthy. Suggested to go to NA, church with me and my daughter, anything. She lies on the couch and sleeps, yells, and burns herself and funiture with cigarettes. She isnt physically hurting anyone, but my 7 year old daughter has to sit here and watch her mother daze in and out all day. This isnt giving my child a good example of what a mother/wife is. I try to explain to her the best I can that "she's sick" without putting her down to much. But she wont leave. She stays here to make shure theres someone to wait on her, clean up after her buy her cigarettes, drugs, etc. I dont like to give her money, fetch her pop and food or clean up after her. But if I dont do these things she will flip out and start saying hateful evil things. She will not hold back with our daughter there. I feel like I need to keep our home peaceful, clean and as "normal" as I can. For my childs sake. She's my main priority at this point. I filed for emergency and full custody and was awarded these things as of last week. I have a "do it yourself" divorce package from legal aide and will be filing it next week with the courts. But when my wife recieves a copy of this being filed in the mail she will stop at nothing to make our lives a living hell. I dont have the money to hire a lawyer. I am financialy in hard place. I had to drop outta collage and limit my hours at work to make shure my child is takin care of. If I file for a divorce along with having custody of my child she will most likily lose her medicad(state insurence) and this will prevent her from going to ER's and doctors for drugs as well. Is there any way of getting her outta our home till the divorce is final? Please help! Thank you for any help you could provide us.
