Oh God, help me

Please Lord help me. My sister as we all know is in rehab. The courts have made her go. The place is run by the probation dept. So far I have spent $2000 on her stay there. She has had to have stitches on her head because of an accident while cleaning the dining room there. I had to pay for them to take her to the ER. She has also gotten a infection on her skin, I have had to pay for them to take her to the doctor 3 times now. plus her medication. I got a call today for more money for this infection. If I don't pay she has to walk aroound infected. I also had to pay $150 Sunday so that her 5 year old could come see her for mother's day. There did not put the money in her account however so She doesn't get to see him or call him for 2 more months. It is crazy......Any suggestions on what the hell to do.
