However, in a preview shared by , the TV personality admitted that she's been "battling mental health" and depression "big time."
"Is it worse when you're by yourself versus when people are here?" the doctor inquired.
"By myself. That's why I kinda felt like I needed to just take a break and not think about diets, relationships. Just clear my mind. Just work on me," she explained.
Tammy revealed that she's been coping with her issues by partying and has picked up some unhealthy habits along the way.

"Drinking, smoking. I started vaping," she told Dr. Smith.
When asked how much she'd been drinking, the TV star replied: "Maybe eight bottles a week."
"Like fifths of liquor? Oh wow, Tammy. That's a lot," the Doctor replied, admitting he's "worried" about the quantity.
"Tammy's doing a lot of partying, which raises a concern for me," he later said in a confessional.
"That alone is putting her in severe danger. She says she's focusing on her mental health, which if that was true, I'm all about that," he continued.
"But she's not made any strides to actually do it. So I'm a little concerned that she's actually just using that as an excuse to buy her more time to not work on her activity level, making some changes in her diet, or anything further than that."
SCARY TURN
The season finale also showed Tammy "stopped breathing" on the way to rehab.
The show's network shared a shocking clip from the upcoming episode on .
In the preview, Tammy sat slouched in her wheelchair while her head was tilted back.
In a confessional, her sister, Amy Slaton, 34, said: "I don't know how her body can hold up. I'm hoping Dr. Smith can intervene with Tammy."
Dr. Smith then 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.
A NEW LEAF
Despite her issues leading up to rehab, a source exclusively told The Sun that the 35-year-old TV star has been making progress with her goals at the Ohio facility.
The source said: "She met with a nurse a few days ago and she 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."
