He's an open book.

Pete Davidson discussed everything from his battle with mental illness to his recent engagement to Ariana Grande in Variety's annual Power of Young Hollywood issue, and the most shocking confession was that he tried to take his own life in the pool at a young age!

"I’ve been in and out of mental health facilities since I was 9. I tried to drown myself in the pool when I was in the fourth or fifth grade. I was trying to get my head stuck in the ladder in the deep end, so I would not be able to get up," he admitted.

Losing his firefighter father in 9/11 totally changed the course of his life.

"If my dad didn’t die, I wouldn’t be a comic. I’d be a construction worker in Staten Island or a basketball coach. I learned what death was. To learn how anything can just be taken away from you early gave me this sense of ‘F— it. Whatever, dude.’ I’m able to do stand-up and f— around because hopefully the worst thing that has ever happened to me happened," he revealed.

Turning to a happier subject, he explained how he popped the question to Ariana Grande, and how grateful he feels to have found his soulmate.

"I didn't want to do something corny. We were in bed hanging, after watching a movie. I was like, 'Will you marry me?' It was really dope," he gushed.

"I'm still convinced she's blind or hit her head really hard. Something is going to happen, and she's going to be like, "What the f— is this thing doing around?" For right now, it's rocking. I never thought I'd meet anyone like her. I can't even put into words how great of a person she is. I could cry. She's the f*cking coolest, hottest, nicest person I've ever met. I'm f*cking living the goddamn dream. I feel like I'm living in a fantasyland," he added.

His rocky life seems to have turned out alright!
