Pete Davidson is not joking around. The “Saturday Night Live” star is setting the record straight on dating with Borderline Personality Disorder, after backlash on social media that criticized how it might affect his current relationship with pop star Ariana Grande.

Last year, the 24-year-old comedian publicly spoke about his struggles with mental health and his Borderline Personality Disorder (BPD) diagnosis, which he attributed partly to losing his firefighter father to the 9/11 terrorist attacks at age 7.

Davidson shared a lengthy message on his Instagram (via E! News) on Thursday night, defending his BPD diagnosis and his new relationship with Grande that was revealed earlier this month.

“Normally I wouldn’t comment on something like this cause like f–k you,” he wrote. “But I’ve been hearing a lot of ‘people with BDP can’t be in relationships’ talk. I just wanna let you know that’s not true. Just because someone has a mental illness does not mean they can’t be happy and in a relationship.”

“It also doesn’t mean that person makes the relationship toxic,” he continued. “Everybody is different and there are a lot of treatments for mental illnesses and I have done/am doing all of them. And I encourage those who struggle to seek help as well it has changed my life for the better.”

Davidson also undergoes regular treatment to manage Crohn’s disease, which he was diagnosed with at age 17. Previously, following a series of “mental breakdowns,” the comedian checked himself into rehab in 2016, the same year he was on the Forbes 30 under 30 list.

“I just think it’s f—— up to stigmatize people as crazy and say that they are unable to do stuff that anyone can do. It’s not their fault and it’s the wrong way for people to look at things,” he added, which is evident in his accomplishments at such a young age.

Davidson has been doing stand-up comedy since he was 16 years old, and joined “Saturday Night Live” at age 20—one of the youngest cast members on the show ever.

“Mental illness is not a joke it’s a real thing,” Davidson concluded on his Instagram this week. “There’s kids out there killing themselves. And it’s f—— horrific. For all those struggling I want you to know that I love you and I understand you and it is going to be okay. That’s all. Love to everyone.”
