If you thought Abby Lee Miller's troubles were over following her release from prison, you'd sadly be mistaken.

Back in April, the Dance Moms star underwent emergency spinal surgery to remove an infection.

Her surgeon Dr. Hooman Melamed told E! News that had Miller not been operated on, she could have faced either paralysis or death.

However, only a day after the surgery, Miller was diagnosed with Burkitt lymphoma, a form of non-Hodgkin's lymphoma, which is cancer of the lymph nodes.

"We're getting an oncologist involved and we have to figure out what the next steps are as far as chemotherapy or radiation or more spine surgery," Dr. Hooman M. Melamed, an orthopedic spine surgeon at Cedar Sinai Marina Del Rey Hospital told PEOPLE at the time.

"Depending on the tumor type, depending on the sensitivity of the tumor "“ it just depends the type but I feel more than yes, she will undergo chemotherapy or radiation."

Miller has been undergoing chemotherapy treatment, she was told there was a chance "she may never walk again," but has vowed to "beat this and not only walk, but dance again."

While Miller has been in rehab for the last four-and-a-half months, it's recently been revealed she's left the facility, because the it has been "too expensive" to stay there.

"She isn't doing good. She left because it's too expensive to stay in rehab," a source told Us Weekly.

"She's home, she can't go anywhere else. She still can't walk. It's really sad."

Luckily, a source close to the reality star said she's been surrounded by a strong support system that's keeping her optimistic.

"She has been open about her diagnosis with her close friends who are in awe of Abby Lee's fighting spirit," the insider shared with E! News.

"Her inner circle is rallying around her with support and regular visits to the Dance Moms star."

Her former student and popular YouTube star Jojo Siwa reiterated the source's claims of Miller's positive outlook.

"Abby is doing great. She's in good spirits, she has great people surrounding her," she told Us Weekly. "[She still] has a couple of rounds of chemo to go through."
