I had nightmares after watching this. The ultracompetitive twin that starved herself to be thin to have an edge over her sister. She couldn't deal with being bigger than her 125 lb twin and starved down to 98 pounds. Regurgitatiting through your feeding tube? Wow.
The one that got me was the destructive little blonde girl who starting crying that she had a double chin when her mother came for visitation. She was skin and bones.
