Darrell Sheets may have been fighting internal demons for years prior to his tragic death.

“Depression is the Devil’s way of attacking us, it knows no mercy, it takes our smiles, it comes and goes, it ruins our relationships, it takes away our happiness, it leads to suicide in some cases, it destroys all thoughts of positivity, it is a 24/7 battle and allows no rest for the suffering,” the reality star wrote in an Instagram post dated June 21, 2018.

“So please next time someone tells you they have Depression, be kind and know that they spend every minute they have breathing suffering!!!” he continued.

The “Storage Wars” star ended his nearly decade-old social media post, which featured a selfie of him wearing sunglasses seemingly on a boat, with the eerily foreshadowing hashtag #trustmeiknow.

Sheets was found dead in his home in Lake Havasu City, Arizona, on April 22. He was 67.

According to a press release from the Lake Havasu City Police Department, Sheets — who suffered a heart attack in 2019 — died from an apparent self-inflicted gunshot wound to the head.

Authorities said Sheets was pronounced dead at the scene and his body was turned over to the Mohave County Medical Examiner’s Office for “further investigation.”

Two of Sheets’ “Storage Wars” co-stars, Dave Hester and Rene Nezhoda, have addressed claims their former castmate was experiencing cyberbullying in the time leading up to his suicide.

“He had this guy, like, really, really tormenting him lately and cyberbullying [him],” Nezhoda said in an Instagram video Wednesday shortly after news broke of Sheets’ tragic death.

“Darrell has been posting a lot about the guy that’s been cyberbullying him and tormenting him, and I really hope [law enforcement] look into that guy and it’s just not a pass,” he added.

Nezhoda reminded fans “just because you watch us on television doesn’t mean you know us” and that “you never know what demons somebody faces and what they go through.”

In his own Instagram video, Hester said he was aware of “some stuff there about cyberbullying” related to Sheets.

“I don’t even know how that exists because I turn that type of stuff off,” he said. “But I’m sure it’s out there. And if it’s happening, or happened, I hope that it’s taken care of the way it should be.”

Sergeant Kyle Ridgway, public information officer for the Lake Havasu City Police Department in Arizona, told Page Six Wednesday they were “aware of these cyberbullying accusations.”

Ridgway also confirmed those claims are “a part of the active investigation” into Sheets’ death.

Sheets appeared in 163 episodes of “Storage Wars” between 2010 and 2023, often alongside his son, Brandon. Together, they earned the nicknames “The Gambler” and “Sidebet.”

After his time on the A&E show, Sheets retired to Arizona.

He was running the antique shop Havasu Show Me Your Junk at the time of his death.
