Fans And Friends Are Worried About Pete Davidson After 'I Really Don't Want to Be on This Earth Anymore' Tweet

Pete Davidson shared cryptic message, implying he's having suicidal thoughts.

The 'SNL' star posted the note on Instagram, saying ... "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."

It's unclear to whom Pete's directing his words, but he adds ... "all i've ever tried to do was help people. just remember i told you so."

Davidson's message seems to be a cry for help -- just minutes before he posted it he responded to Kanye West going after his ex, Ariana Grande, by commending Ye for speaking about against mental health issues.

He said ... "I can't explain to you enough how difficult and scary it is to be honest about stuff like this."

Just 2 weeks ago, Davidson blasted online trolls for bullying him, telling them he wouldn't kill himself no matter how hard they tried to get him to. Ariana responded not long afterward, telling her fans to "be gentler" with Pete and others ... saying she cares deeply about him and his health.

Pete's been very open about his mental health issues recently, which is the reason why his reason tweet is worring his friends, who thinks it's a cry for help.

Machine Gun Kelly tweeted about the situation, saying he's on a plane to see Pete to make sure he's good.

Jon Cryer also just tweeted that he heard Davidson is at 'SNL' and accounted for.

TMZ.com is repoting  Ariana Grande is at the 30 Rock building to see Pete if possible. She tweeted ... "I’m downstairs and I’m not going anywhere if you need anyone or anything. I know u have everyone u need and that’s not me, but i’m here too."

She also apologized for her "dumb joke" about Kanye and Drake's beef that led to the topic of mental health when Kanye went after her. She said ... "i really didn’t mean any harm. all i want everyone to be healthy and happy. so desperately. please. my god." 

Grande also deleted her previous tweets about "triggering" Kanye and commenting on mental health.
