It's her choice. Not everybody who leaves JW's nor is not a JW lead a debauched life. You'll find in regards to biblical morals (if she wants to stick to those) are practiced without fear of shunning by many Christian churches.
I also know someone who was majorly into drugs, stealing, jail, prostitution, etc, who had their entire life turned around when they got help from a Prysberterian (however it's spelt) Church that had drug programs. The past 20 years she's never returned to that and now helps those with drug problems as well. Her church also had specialized training and helpers for depressed and those contemplating suicide, unlike the recently posted Elder's training video, which pretty much said, "Don't commit suicide or Jehovah will kill you at armagedon".
