"The attention and negativity coming from Kanye and his antics is a trigger for (Pete), and he's had to seek out help," an insider told People, who first reported the story on Monday.
The source stressed that, despite calling it quits last week, Davidson "has no regrets for dating Kim and wants it to be made very clear that she's been nothing but supportive of him throughout their relationship".
On August 5, an insider confirmed to Page Six that Davidson and Kim, 41, had called quits after nine months of dating.
Kanye has continuously criticised Davidson, who he dubbed Skete, ever since he was first linked to Kardashian in October 2021.
Earlier this year, West released a video for 'Eazy' that had him literally kidnapping and burying a cartoon version of Davidson. He also rapped about "beating Pete Davidson's a**".
