“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 tells PEOPLE.

Pete Davidson is seeking help for online harassment he has received at the hands of Kanye West, a source close to the comedian tells PEOPLE.

Beginning in April of this year, the Saturday Night Live alum, 28, “has been in trauma therapy in large part” due to threatening posts that West, 45, has posted numerous times on social media while Davidson was dating the rapper’s ex-wife, Kim Kardashian.

“The attention and negativity coming from Kanye and his antics is a trigger for [Pete], and he’s had to seek out help,” the insider says.

The source adds that Davidson, who recently split from Kardashian, 41, “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.”

“Moving forward he just wants to focus on his career,” the insider adds of Davidson.

A representative for West did not immediately respond to PEOPLE’s request for comment.

Last week, Davidson and the SKIMS mogul decided to go their separate ways after nine months of dating.

“Part of the reason they split was because of their busy schedules,” an insider previously told PEOPLE of the couple, who were first romantically linked in October 2021. “They both travel all the time and it was hard.”

After their breakup made headlines, West reacted on Instagram Monday morning with a since-deleted post featuring an image of an altered New York Times newspaper with a headline that read, “Skete Davidson Dead at Age 28.”

Below the headline, another part of the fake mockup said, “Kid Cudi meant to play funeral but fearful of bottle throwers” — a nod to an incident that occurred at the Rolling Loud Miami festival last month, where fans in attendance threw water bottles at him. (Cudi, 38, and West have admitted to beef of their own.)
