Christy says her 17-year-old son, Cameron, is completely out of control. She says he’s verbally and physically aggressive, vapes marijuana, skips school, and has no respect for authority.

Cameron has been living with his grandmother, Mary, for over a year. He says he moved in with Mary after Christy kicked him out of the house for refusing to take a drug test. Now he says he only sees Christy every couple of weeks.

“I don’t want to get back with her – I really don’t,” says the 17-year-old.

Cameron claims that when he was younger, his mother stood by while allowing someone to hit him, lock him in his room and board his windows up.

“It made me angry and sad,” says Cameron. “And my mom just watched.”

Christy says, “I did fail to protect him for a certain period of his life, and I regret that.”

When Dr. Phil asks what she told herself while she was allowing that to happen, how does Christy respond?

This episode of Dr. Phil, ‘“17 and Extra Mean: Help My Pot-Smoking, School-Skipping Teen!”’ airs Tuesday.

And later, when Dr. Phil introduces Cameron to life development coach Mike Bayer, does Cameron say he’s ready to turn his life around?

Dr. Phil airs Monday – Friday. Check your local listings to find out where to watch.
