‘Saturday Night Live’s’ Pete Davidson Responds to Mental Illness Trolls Davidson, who deals with Borderline Personality Disorder, was attacked by online commenters this week After rumors that he and Ariana Grande were casually dating. ...I been hearing a lot of ‘people with bpd 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. 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. Davidson also encouraged people who are struggling with mental illness to seek help. 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.
