All these details are so chilling.

Demi Lovato's assistant was the one who called 911, and she asked the dispatcher if the emergency responders could turn off their sirens so it wouldn't alert the neighbors that something was wrong, TMZ reports.

The "Skyscraper" songstress was found unresponsive in bed after an all-night party at her Hollywood Hills home, and apparently she was discovered just in the knick of time. "She could have died," a source told the outlet, noting that the overdose was incredibly serious.

The 26-year-old is still hospitalized, and her next move is still up in the air. Her friends and family want her to go to rehab and work on her recovery, but she has to be the one who decides that.

"The thing about an addict is that you become so good at hiding it. She’s a really smart girl. When she had work commitments, she could pull it together. But that’s how she’s always been, and this might not be her rock bottom. Demi has to want to get help. She can’t be forced into rehab or treatment. It won’t work," a source dished to People.

We really hope she gives sobriety another shot.
