‘SNL’ star Pete Davidson has borderline personality disorder

Pete Davidson revealed that he has borderline personality disorder.

The “Saturday Night Live” star, 23, explained that he thought the symptoms he had been experiencing were because of his “pothead” nature.

“Around October [or] September last year, I started having these mental breakdowns where I would, like, freak out and then not remember what happened after. Blind rage,” said Davidson on “WTF With Marc Maron” Monday.

Davidson, who announced in March that he was sober for the first time in eight years, thought rehab would help.

“I never really did any other drugs, so I was like, ‘I’m gonna try to go to rehab. Maybe that’ll be helpful,'” Davidson said. “So I go and I get off weed. They told me there, they’re like, ‘You might be bipolar,’ and I was like, ‘OK.’ So they’re like, ‘We’re gonna try you on these meds.’ And then I got out [of rehab], and then I started smoking weed again — and I’m on meds.”

One “really bad episode” later, Davidson returned to his doctors, who diagnosed him properly.

“I found out I have BPD, which is borderline personality disorder,” he explained. “One of my psychiatrists [diagnosed me]. He was always saying before this big meltdown, ‘You’re probably bipolar or borderline, we’re just going to have to figure it out.'”

Davidson admitted he still struggles with learning how to live with his diagnosis, but his new medication helps.

“It is working, slowly but surely,” he said. “I’ve been having a lot of problems. This whole year has been a f–king nightmare. This has been the worst year of my life, getting diagnosed with this and trying to figure out how to learn with this and live with this.”
