“It wasn’t planned,” she said while starting to cry. “We just came together, Robert and I, and I said, ‘We’re going to do this because we’re going to help someone.’”

Mary explained that her son did “not plan what he was going to say” in front of the cameras and neither did she.

“I just said what I felt,” she said as Cohen, 56, reached over to take her hand and assure her she “did great.”

Mary went on to share that Robert’s wife also sought treatment at a rehab center and is “still in there.” She raved about her husband, Robert Cosby Sr., helping both her and her son throughout the ordeal and how he was “able to guide Robert [Jr.] better.”

During the Nov. 27 episode of “RHOSLC,” Mary asked Robert Jr. to tell her the “honest truth” about what was going on with him following a period of reclusiveness.

“I’m taking Xanax,” he admitted, referring to a medication used to treat anxiety. “I just took half to chill me out, and then I take an Adderall to balance out Xanax.”

Robert Jr. described his life as “chicken unseasoned,” but when he gets high, “it’s adding seasoning to it.”

“At first, I was like, I’m just gonna stick to natural stuff. And then, I went to a party, and someone gave me a Xanax. And then I was like, ‘Oh, I like this,’ so I started buying it,” he recalled.

“Then I started doing Xanax with acid and then molly with Xanax, because I like Xanax, so I mixed it with everything — Xanax and cocaine.”

He then asked his mom, “You know the regular 30 milligram Oxys? I noticed this was, like, a turning point for me. … I was taking 10 at once, and I couldn’t even feel it. I couldn’t feel it at all.”

Mary cried throughout the heart-to-heart and told Robert Jr. that she “love[s] [him] more than anything, more than anything in this world” and would “try to help” him.

“You’re my friend, you’re my son, you’re my gift,” she continued. “God gave you to me. You’re the only thing that ever made me happy. Before I had you, I was never happy. You came in, and you were so real. You was everything I hoped for in a person.
