A “depressed” mother fatally sh0t her husband and two young children before turning the g::un on herself in their New Hampshire home – just days after sharing her ongoing struggles in a chilling video on social media, authorities said.

Emily Long, 34, who was found with a self-inflicted g::unsh0t wound to the head, allegedly k!lled her husband, Ryan Long, 48, and two children, Parker, 8, and Ryan, 6, in an apparent mu::rder-suic::ide at their ill-fated Madbury home early Monday morning, according to the New Hampshire Attorney General’s Office.

Both youngsters were sh0t in the head, while the family’s patriarch – who was reportedly battling terminal cancer – sustained multiple g:::unsh0t wounds, the state’s chief medical examiner concluded.

“It was a perfect family as far as we knew,” neighbor Bevy Ketel told WBZ-TV.

“It’s just shocking. We didn’t see it coming.”

Police discovered the grisly scene Monday night after receiving a haunting 911 call reporting multiple deaths inside the family’s m@ssacred home.

A g:::un was located near their lifeless bodies, officials said.

The couple’s three-year-old child – the lone survivor of the slaughter – was found alive and unharmed inside the house and is now in the care of family members.

Investigators said they have since learned of serious concerns and ongoing issues at the time of the violent rampage, but didn’t elaborate.

“One of the biggest questions they have right now is motive, why?” Assistant Attorney General Ben Agati told WCAX.

“And I think that’s probably one of the more difficult things that they are trying to grasp to understand how this came to be.”

While a motive remains unclear, the family’s matriarch – who worked as director of operations at the restaurant chain Wing-Itz, according to her LinkedIn – often posted on social media about her struggles and despair as she coped with her husband’s terminal cancer diagnosis.

Ryan, a school psychologist at Oyster River Middle School in Durham, was reportedly diagnosed with glioblastoma, a highly aggressive form of brain cancer.

In a TikTok posted just two days before police made the horrific discovery, Emily told her nearly 8,000 followers that her children were “definitely struggling” and she herself had been “really depressed” as she tried to restore healthy habits and normalcy in the home as her husband’s health declined.

“I am determined to create normalcy,” she said in her grim video.

“I have been struggling so much and really depressed and just have really become reclusive, and just wanted to be with my kids and my husband. That being said, I’m making a change and it is starting today … And I’m making a point to get out of my depression and do this for my family.”

The tragedy remains under investigation.
