Amber Portwood, the 16 and Pregnant and Teen Mom star who was sentenced to five years in prison this week after opting out of a drug-treatment program, recently attempted suicide, according to a jailhouse interview Portwood gave to Good Morning America. “I had taken 30 Suboxone [pills] within about three days,” Portwood said. “The depression took over.”

This isn’t the first time Portwood attempted suicide. According to the interview, ex-boyfriend Gary Shirley called 911 after a suicide attempt by Portwood last year.
