Hannah Berkowitz is 20 years old. When she was a senior in high school her life flew off the rails.
She was getting high on whatever drugs she could get her hands on. She was suicidal. Berkowitz moved into a therapeutic boarding school to get sober, but could only stay sober while she was on campus during the week.
"I'd come home and try to stay sober really hard — really, really hard," says Berkowitz. "Sometimes I'd make it through the weekend, and sometimes I just couldn't make it. It was white-knuckling it, just holding on."
