Others praised Tammy for her recent weight loss efforts after Monday night's season finale revealed the progress she's made in her journey.
One said: "Hey Tammy, I know you get a lot of hate but I just wanted to say how amazed I was with your progress in the last episode. Keep going girl!"
Another added: "This weeks episode had me in tears I feel every thing you was saying Tammy. Keep up the hard work and accept the help you are definitely worth it!"
"So proud of you Tammy for changing your mind and going to to rehab! This last episode made me tear up glad you are here another day," one chimed in.
WEIGHT LOSS
Tammy's brother Chris Combs gave an update on his sister's health in the latest episode, telling the camera: "So she's lost 100 - I think she told me 115lb in total in 30 days.
"I'm overjoyed that's she's ready to get on this train and start rolling down the tracks."
This means Tammy could be at around 534lb now. She is planning to stay in rehab for eight months.
December would have been the TV star's first full month in rehab, with January being her second full month.
If Tammy stays on track, it's possible she has lost another 50 to 100lbs since the finale was filmed.
Dr. Smith promised Tammy that if she’s able to dip under 500lb during her stay, he’ll arrange for her to come directly to him for weight loss surgery when she leaves the facility.
According to Mayo Clinic, candidates for weight loss surgery must show an effort to lose weight six months prior to surgery, have a BMI of 35 or higher, and at least one obesity-related medical condition.
'HER BODY IS SHUTTING DOWN'
Also during the season finale, Chris revealed Tammy was rushed to the hospital one day after arriving at rehab because she couldn't breathe.
"They're just telling us that her lungs have given up, and like her body is shutting down," their sister Amanda said.
Tammy was placed on a ventilator and then put into a medically-induced coma at the hospital.
"They didn't know if she was going to make it through the night. Or make it through the next hour," Chris said.
When Tammy woke up, she was given a tracheotomy - which involved having a breathing tube inserted in her throat.
After three weeks in the hospital, she was able to return to rehab.
UNHEALTHY HABITS
Tammy's family feared for her well-being after she resorted to unhealthy habits like smoking, drinking, and indulging in fatty foods.
She previously said about her partying ways: "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."
Tammy added: "But now, I'm at the point where I don't care. I'm gonna be me."
She also admitted to drinking eight bottles of liquor a week to cope with her mental health issues.
Tammy's family expressed their concerns about the the 35-year-old's future on last week's episode, predicting that she'll be dead in five years if she continues down this path.
