Friends rally around Pete Davidson after worrying Instagram post

This article deals with mental health problems, including attempted suicide.

Pete Davidson's friends have rushed to contact him after the comedian posted a concerning message on his Instagram account.

Saturday Night Live (SNL) star Davidson posted a message that implied he wanted to kill himself on Instagram on Saturday (local time).

"I really don't want to be on this earth anymore," he wrote.

"I'm doing my best to stay here for you but I actually don't know how much longer I can last. All I've ever tried to do was help people. Just remember I told you so."

Former co-star Jon Cryer quickly posted on Twitter asking people to help locate Davidson, saying he tried to contact the comedian but couldn't get through.

Soon after he posted to say Davidson had been located at SNL.

"We are thinking of you, Pete.  You are loved," he wrote. "And just a heads up, when you finally turn on your cell, it's gonna go apeshit for a little while."

Davidson's close friend Machine Gun Kelly tweeted in the midst of the drama that he was travelling to see his friend and support him.

"I'm in the plane now on the way to see Pete. Gonna make sure he's good, I promise. Can't have my boy in the darkness like that," the rapper wrote.

Davidson, who is open about his borderline personality disorder, has been on SNL since 2014 but rose in prominence this year after a short and highly public relationship with singer Ariana Grande.

The pair were briefly engaged but called it off in October.
