Bobbi Kristina Brown’s boyfriend Nick Gordon admitted to substance abuse and talked about his anguish over his girlfriend’s condition during an interview on the "Dr. Phil" show, which aired Wednesday. In the interview, Gordon blamed himself for Bobbi Kristina's hospitalization.

Gordon, who appeared on the show along with his mother, Michelle, admitted to substance abuse, and broke down as he expressed his feelings for the daughter of the late Whitney Houston and Bobby Brown. Michelle reportedly said on the show that her son had tried to kill himself by taking drugs like Xanax and Unisom.

"He has blamed himself for [Bobbi Kristina] being in the condition that she's in, he's torn up by that," Michelle reportedly told Dr. Phil. "He's dealing with it by drinking. I've begged him to stop."

The 22-year-old aspiring actress remains in a medically induced coma after she was found unresponsive in a bathtub in her suburban Atlanta home on Jan. 31, following which she was hospitalized. Gordon, who first spotted Bobbi Kristina unconscious in the bathtub, reportedly performed cardiopulmonary resuscitation (CPR) in a bid to revive her as he waited for paramedics to arrive.

"I've been so strong for so many people for so long, so please don't tell me to man up," Gordon told Dr. Phil. "My pain is horrible, my head hurts, I have panic attacks."

Earlier in the episode, Dr. Phil explained that he wanted it to be a straight interview, but "when we arrived, we realized this is a serious situation and if Nick didn't get help, he could end up dead." Soon after the interview, Gordon checked into rehab following Dr. Phil's multiple requests.

The former psychologist also spoke to Michelle, who claimed that Gordon had also performed CPR on Whitney Houston when she was found in a bathtub by her assistant in February 2012, following which she was pronounced dead at the age of 48.

"He administered CPR to her. He called me when he was standing in front of body,” Michelle reportedly said, in the interview.

However, Dr. Phil later revealed that a representative for the Houston family had refuted the claim. "Nick Gordon did not perform CPR on Whitney Houston and the police report reflects that," the representative said, according to E! News.
