Machine Gun Kelly is speaking out about his mental health issues.

The “Papercuts” singer gives fans an intimate inside peek into his life in his new Hulu documentary Life in Pink, which aired Monday.

About halfway through the film, the star (born Colson Baker) — who is engaged to actor Megan Fox — opens up about his descent into darkness following his father’s death in 2020.

“I flew to my dad’s apartment to clear all this stuff out. I had this really weird interaction with this neighbor who told me all these things I didn’t want to hear,” he says in the documentary of his father, who died on the one-year anniversary of the publication of his Hotel Diablo record. “That f—– me up even more because I couldn’t get closure on it. I wouldn’t leave my room and I started getting really, really, really dark.”

“Megan went to Bulgaria to shoot a movie and I started getting this really wild paranoia. Like I kept getting paranoid that someone was gonna come and kill me. I would always sleep with a shotgun next to my bed, and like, one of the days, I just f—— snapped,” he continued.

“I called Megan, I was like, ‘You aren’t here for me,'” he elaborated. “I’m in my room and I’m like freaking out on her and dude, I put the shotgun in my mouth and I’m yelling on the phone and like the barrel’s in my mouth. I go to cock the shotgun and the bullet as it comes back up, the shell just gets jammed. Megan’s like dead silent.”

The terrifying experience was a watershed moment for the musician, who understood afterwards that something was “not right” with how he was feeling.

He recalls Fox, 36, and Baker’s 12-year-old daughter, Casie, expressing their concern for him.

“They simultaneously came at me with this like, ‘I want to like, be able to see in your eyes. I don’t want to like be talking to you through a veil anymore. I want to see you as my father and I want to see you as my husband-to-be,'” he reveals in the film. “I was like, ‘I need to kick the drugs, for real this time.'”

The actor has been candid about his ups and downs in recent years. In an issue of Interview magazine in December 2020, he revealed that he was getting counseling for his problems.

“Currently, my drug of choice is happiness and commitment to the art, rather than commitment to a vice that I believed made the art,” he claimed at the time. “I’m taking steps. I had my first therapy session last Thursday. That’s the first time I ever went, ‘Hey, I need to separate these two people,’ which is Machine Gun Kelly and Colson Baker. The dichotomy is too intense for me.”

He also focuses on Fox’s good influence on him in his new Hulu documentary.

“Megan became like the sun to me — like the one that I revolve around and gives me life and like helps me grow,” he declared. “It’s just like every fairytale that they never told you in school, that they never taught you. Like the passion between us is otherworldly. I know I’ve known her in so many other lifetimes.”

The couple, who met on the set of Midnight in the Switchgrass and declared their relationship in July 2020, got engaged in January this year and sealed the deal by drinking “each other’s blood.”
