I would not pick her up but I would get her out of that toxic school. She needs a fresh start somewhere else.
FWIW I worried about our zoned public HS because I heard stories about the drugs in the bathrooms, kids having sex on the stairwells, overcrowded spaces. But my 2nd just graduated and both kids had a good experience there. Had mostly great teachers, got involved in extracurriculars, made new friends, and were well prepared for college. So from this vantage point I wouldn't put a lot of stock in rumors of "drug problems." These days EVERY HS has issues with drugs for some students. I'm sure they are at this private school too.
