Saturday Night Live cast member Pete Davidson shared an alarming message on Instagram, claiming, "I really don't want to be on this earth anymore," before deleting his account on Saturday.

Davidson posted a screenshot of an iPhone note which read, “I really don’t want to be on this earth anymore. 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,” he continued, adding a single red heart emoji to the post that didn't include a caption.

Davidson later deleted his Instagram account entirely on Saturday.

His ex fianceé, Ariana Grande, shared since-deleted tweets in which she said she wanted "everyone to be healthy and happy" after the comedian's post.

“Man I’m so sorry I told a dumb joke. I really didn’t mean any harm,” she tweeted. “All I want everyone to be healthy and happy. So desperately. Please. My God.”

“I’m downstairs and I’m not going anywhere if you need anyone or anything,” she added. “I know U have everyone U need and that’s not me, but I’m here too.”

TMZ confirmed that Grande was at the 30 Rock building in New York City to see Davidsion if possible.

Actor Jon Cryer, who attempted to reach out to Davidson after the post, revealed that he spoke with SNL reps who confirmed that the comedian was at the NBC studios and "accounted for."

"Am hearing Pete Davidson is at SNL and accounted for. We are thinking of you, Pete. You are loved," Cryer tweeted on Saturday.

A public information officer with the New York Police Department told People magazine that officers were sent to do a welfare check on the 25-year-old after the Instagram post.

Rapper Machine Gun Kelly, a friend of the comedian, revealed that he was on his way to check on Davidson and "make sure he's good."

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

Davidson, who has borderline personality disorder, credited Kanye West in an earlier post for speaking publicly about mental illness during his ongoing feud with fellow rapper Drake.

“Bravo Kanye West for standing up for yourself and speaking out against mental health,” Davidson wrote on Instagram.

“I can’t explain to you enough how difficult and scary it is to be honest about stuff like this. We need people like Kanye,” he added.

"No one should ever point finger at you for your bravery in speaking about mental health. I’m seriously disgusted," Davidson continued, which many believed was directed at his ex-fianceé, although not mentioning Grande by name.

On Saturday morning, West addressed a tweet Grande shared on Thursday promoting her new song "Imagine," which dropped hours after the rapper's Twitter rant directed at Drake.

“I know Ariana said this to be cool and didn’t mean no harm but I don’t like even slightest level of slight commentary from someone I know loves and respects me,” West tweeted.

While many Twitter users reacted to the West's rant, Grande jokingly attempted to divert attention to herself and Miley Cyrus, both of whom released songs early Friday morning.

“Guys, I know there are grown men arguing online rn but Miley and I dropping our beautiful, new songs tonight so if y’all could please jus [sic] behave for just like a few hours so the girls can shine that’d be so sick thank u,” Grande wrote on Thursday.

Earlier this month, Grande showed support of Davidson after the 25-year-old shared a written statement via Instagram about how he intended to keep living despite frequent suffering from suicidal thoughts and borderline personality disorder.

"I know u already know this, but I feel I need to remind my fans to please be gentler with others," she wrote. "I really don't endorse anything but forgiveness and positivity. I care deeply about Pete and his health. I'm asking you to please be gentler with others, even on the internet."

Grande continued, "I've learned thru [sic] my own mistakes not to be reactive on socials, so I do understand, but you truly don't know what anybody is experiencing ever, regardless of what they choose to display on social media or how they may appear in public. I can promise u that so please let whatever point you're trying to make go. I will always have irrevocable love for him and if you've gotten any other impression from my recent work, you might have missed the point."

Davidson claimed he had been consistently bullied online over the last nine months, which coincided with the couple's engagement and breakup.

"I've spoken about BPD and being suicidal publicly only in the hopes that it will help bring awareness and help kids like myself who don't want to be on this earth," he wrote. "I just want you guys to know. No matter how hard the internet or anyone tries to make me kill myself. I won't. I'm upset I even have to say this."
