Why was Lena placed in therapy as a child as noted in the memoir, Not That Kind of Girl?

Lena suffered most of her life from fear that she could not quite define. Even as a little girl, she was worried about the food she ate and diseases she might be catching. It was debilitating to her social and family life and education. Her parents placed her into intensive therapy where she was diagnosed with Obsessive-Compulsive Disorder. She was on medication for many years to combat the effects of the disorder. She stayed in some form of therapy throughout her late teens. She eventually was able to do without medication and without therapy and recognize the warning signs when the condition was once again rearing its ugly head.
