You continue to be a good person. Keep your head up, be honest, be honorable. Don't get in yelling matches with a wayward. They used emotional manipulation and love to instigate fights. Why? Because they feel horrible about themselves and what they're doing but they're foolish wayward pride won't admit it so if you're being the adult, doing GAL, and living a clean honorable life, that can cause them to lash out but in the end, assuming she's not actually a sociopath or just plain bad person (some are), she'll respond positively.
If you're authentic, honorable, and a person worth of respect, then you'll get respect.
