“Storage Wars” star Darrell Sheets’ last words were telling his girlfriend to “go back to bed” before his shocking death in April.

According to a Lake Havasu City Police incident report obtained by Page Six, an unnamed woman told police detectives that Sheets got out of bed late after experiencing insomnia most of the night.

She recounted that he then asked her to “go back to bed” while standing in the doorway of his office. Shortly after, she said she “heard a single gunshot.”

The unidentified woman also claimed in the report that Darrell had had a “verbal” argument with his son, Brandon Sheets, at their Arizona home over “family drama.”

Darrell allegedly received an angry text from his daughter-in-law that left him “sad and upset,” noting that he was “devastated” and “sad as hell” following the contentious visit with his son.

The reality TV star’s girlfriend also shared heart-wrenching details about his final moments in her 911 call, obtained by TMZ on Thursday.

After the A&E star’s partner “heard a gun go off” in their home, she dialed the emergency dispatch service and said, “I think he just killed himself. Yeah. Darrell.”

In the audio, she clarified that she had not “see[n] anything” because she “did not want to look.”

Audibly shocked over the situation, she told the operator, “I can’t believe it. I know he’s been just frustrated with this no sleep and his kids. Terrible, terrible.”

The reality star left a handwritten suicide note that detectives located inside a “black bin” inside a closet following his passing.

The Lake Havasu City Police incident report summarized the note as reading, “I could not take anymore the Facebook bullying, f—k you [redacted].”

Per the report, “the writing appeared to be shaky.”

Darrell was found dead on April 22 of a self-inflicted gunshot wound to the head. The Mohave County Medical Examiner’s Office subsequently confirmed in May that he died by suicide.

His “Storage Wars” castmates Laura and Dan Dotson claimed he was living in fear over alleged cyberbullying before his death.

Sergeant Kyle Ridgway previously told Page Six, “We are aware of these cyberbullying accusations and that is a part of the active investigation.”

Brandon — who appeared on the series with his father from 2010 to 2017 — mourned his father’s death in an emotional Instagram upload.

“My heart is so broken….I love you Dad and I will do my best to live in your honor and respect our Family,” he wrote in part in an April 30 Instagram post.
