Tammy and Amy have always shared a close bond and have been through a lot together. They rely on each other for support in a multitude of different ways. It is common for siblings to have misunderstandings and arguments, but sometimes, it goes farther than that for Tammy and Amy. They have a complicated love-hate relationship that has extreme highs and lows.  Here are some of the most shocking and dramatic quotes from the show explained:

"Try Being My Size, Amy. You Don't Know How It Is."

In season 1, Tammy and Amy started trying to lose weight. Along with a healthy diet, the doctor recommended daily exercise in their routine. Tammy’s weight made it difficult for her to move around without being in pain, but she frequently used it as an excuse to rely on Amy for everything. Her sister encouraged her to start doing things for herself so she could begin making progress. Tammy quickly became frustrated and angry, leading to an argument between the two sisters. Amy tried to explain that her weight also made it difficult for her to do things, but she still made an effort. That’s when Tammy hit her breaking point and said, “Try being my size, Amy. You don’t know how it is.”

"I Don't Want To Bury My Sister."

Despite the support of her family, Tammy's food addiction has continued to spiral out of control. The growing concern from her siblings has intensified with each passing season. Her love life has been detrimental to her success as she puts her health on the back burner. Without Tammy trying to make any significant changes, her family’s efforts to help are basically futile. In season 2, Amy had a candid conversation with her older brother, Chris Combs, about Tammy’s future. They were concerned that if she continued overeating, it could lead her to an early grave. Amy was emotional at the thought of not being able to help Tammy, saying, “I don’t want to bury my sister.”

"Amy Needs To Quit Being Lazy."

Since Tammy’s mobility is limited, she requires assistance with daily tasks. This responsibility fell on Amy’s shoulders the majority of the time. Once she gave birth to her son Gage Halterman, she realized that she couldn’t be Tammy’s full-time caretaker. Trying to balance motherhood and Tammy’s frequent demands became too much to handle. In season 3, Amy quickly realized that Tammy would benefit from a home health nurse to help care for her. She knew the idea wouldn’t go over well with Tammy, and broke the news at a family barbecue to have support. As expected, Tammy was upset, and unabashedly told the producers, “Amy needs to quit being lazy and pushing the issue of the nurse.”

As Tammy’s health declines, she continues to shift the blame and refuses to take responsibility for her actions. Until she can start appreciating her family’s help, things may never change. Hopefully, Tammy and Amy’s health and relationship will continue to improve if 1000-lb Sisters returns for season 4.
