Thirteen-year-old Jonelle’s mother, Jennifer, and older sister, Chloe, say they’re at their wits’ end due to the teenager’s uncontrollable fits of rage.

Jennifer says her youngest daughter’s constant outbursts and defiant behaviors have completely worn her out, while 19-year-old Chloe claims that Jonelle is aggressive and mean to everyone in the family.

“During one of Jonelle’s latest flip-outs, she grabbed my head and my ear and was ripping my hair,” claims Chloe. “My biggest fear with Jonelle is that she doesn’t know her own strength. I don’t know how far she’s willing to go.”
