Family members of "America's Next Top Model" finalist Renee Alway are deeply concerned the model's in too deep with drugs -- now they want to recruit the big guns to help, like Dr. Drew or Oprah.
TMZ broke the story ... Renee was arrested last month for attempted burglary -- after cops say she was hiding out in a Palm Springs home that wasn't hers. They also say she had a gun and charged her with possession of narcotics.
We spoke to Renee's sister who tells us ... Renee has a serious drug problem and can no longer take care of herself. She says she's homeless and the night she was arrested she was in "survival mode."
Renee's mother tells us ... the model's substance abuse has gotten so bad, they had to cut her off. "We stopped giving her money, which was feeding her drug problem."
Now the family just wants to see Renee get better, and say they need the best of the best to make that happen. Her sister says, "I am trying to find her some professional help. I would like to get her help from Dr. Drew, Dr. Phil or even Oprah."
Renee is currently behind bars at a correctional facility in Banning.
