Cara Delevingne’s Friends Desperate for Her to Get Therapy and Rehab

Cara Delevingne‘s friends say she’s in a bad way — struggling with issues that go beyond substance abuse — and their desperation to get her help is becoming increasingly obvious.

One of the model’s closest friends, Margot Robbie, was visibly distraught this week shortly after leaving Cara’s L.A. home.

Sources with direct knowledge tell TMZ there’s good reason Margot’s emotions came pouring out that day. We’re told Cara’s been struggling for a while now, initially with mental health issues, but now the people closest to her believe she needs rehab too.

We’re told Margot and other friends are advocating for Cara to immediately get into a treatment program that includes mental therapy as well as substance abuse treatment.

You might recall, Cara and Margot went on vacay together in August … traveling to Spain with other friends to celebrate Cara’s 30th birthday, and since then she’s appeared increasingly erratic in public.

Last week, she looked totally disheveled and seemed confused after initially boarding one of Jay-Z‘s private jets in Los Angeles. The flight never took off, and she got off it 45 minutes later.

The day Margot went to visit Cara … she was supposed to be at her own NY Fashion Week event. She never made it to NYC.
