2. Thumb Sucker, Bodybuilder

Lauren used to be addicted to drugs and alcohol, now she's addicted to extreme bodybuilding. She works out up to six hours a day, six days a week. 24-year-old Rhonda can't stop sucking her thumb while sniffing a scrap of her childhood blanket. The safety and comfort the thumb sucking gave her during her parents divorce, has now become an isolating social behavior she can't let go.
