1,000-lb Sisters’ Tammy Slaton ‘stops BREATHING’ on the way to rehab after partying with friends in season finale teaser

1,000-lb Sisters' Tammy Slaton reportedly "stopped breathing" while on the way to rehab after she had been partying up with her friends during the season finale teaser.

TLC shared a shocking clip from an upcoming episode of 1,000-lb Sisters on Instagram.

In the preview, Tammy, 35, sat slouched in her wheelchair while her head was tilted back.

During her confessional, Amy Slaton, 34, said: "I don't know how her body can hold up. I'm hoping Dr. Smith can intervene with Tammy."

Amy had previously feared that her sibling could be dead in about five years.

Dr. Smith asked Tammy: "Would you consider possibly going back to rehab?"

The reality star confessed she was "ready" to go back.

While in the back of the van, Tammy said she was "feeling sleepy" before she "quit breathing."

The caption stated: "All good things must come to an end" with a crying emoji.

Tammy was previously featured on the TLC show as she was partying, drinking, and smoking, which caused fans to be concerned about her bad habits.

The TV personality had been struggling to lose weight and reach her goal of 550-pounds from 639-pounds. 

'I DON'T CARE'

In a previous clip from the reality show, Tammy was picked up by her friends Rob, Ralph, and JT to hang out.

During her confessional, she said: "We've just been drinking, vaping. As a teenager, I wasn't doing any partying. I was super shy about my weight and I didn't really have many friends."

She added: "But now, I'm at the point where I don't care. I'm gonna be me."

As the clip continued, Tammy vaped in the car before stopping at a liquor store and asked for "one bottle of whatever and eight shots."

Tammy and her pals arrived back at her home to drink and eat pizza.

She confessed: "We don't eat healthily. Because for me, if I eat something like pizza or pizza rolls, the bread soaks up the alcohol and the grease helps so we don't get too hungover."

'WON'T REACH HER GOAL'

A source exclusively told The Sun that the 35-year-old TV star has been making progress with her goals at the Ohio rehab facility.

The source said: "She met with a nurse a few days ago and the nurse said she's improving tremendously.

"I've also seen that she's increased physical activity, which is amazing. She's able to do more things on her own."

The insider continued: "She used to smoke and said she was going to quit, but then she turned to vaping.

"But now she quit almost cold turkey."

The source claimed: "She needs people in her life who are going to tell her what it's like to be okay.

"If she's constantly hanging around people who are overweight, she won't reach her goal."
