What Is Going on With Karina's Head Injury?

"I was so terrified because I know this person is not who I think that they are," she says. "The walls were sort of closing in on her and she checked herself into a mental health facility where we live" She's calling me, updating me but doesn't answer my phone calls most of the time. Karina eventually gave up when she admitted what happened? And she had to involve her parents.
