“Love on the Spectrum” star Pari Kim’s mother, Esme, has died after battling breast cancer.

In a heartbreaking Instagram post Wednesday, Kim — who was introduced to viewers in Season 3 of the hit Netflix show — wrote about her grief.

“It feels like everything is becoming a train wreck and that there are two sides of yourself constantly fighting: the sad, lonely girl missing what was cruelly and unfairly taken from her at such a young age and the girl who has to stay strong and positive because she can’t give up if she wants to keep moving forward,” she wrote.

Kim, 24, noted that “not every train track is a smooth ride.”

“Sometimes the going gets rough and you need other trains to help you pull through and carry the weight of the world on your shoulders. 😢🕊️,” she wrote.

“It’s difficult to keep chugging along when your guardian locomotive reaches the end of the line but you have to keep going somehow even without her.”

Kim also commented on her post, “F—k cancer button.”

Kim later shared a message for her followers on Instagram about appreciating their parents.

“If you still have parents and they are loving and caring to you, please be grateful and know how lucky you are!” she posted. “Time is precious and I didn’t expect to lose both of them so young!”

Kim’s dad, Henry Kim, died in October 2020. According to his obituary, he passed away unexpectedly.

He was 55 years old.

Esme died following her battle with stage 4 breast cancer at 61 years old, Netflix confirmed to the US Sun. Esme was shown battling cancer during filming of the show.

Kim shared in an episode of her mom, “She does have breast cancer right now but she is on treatments so I’m hoping she can stay around and stay around for awhile. I’m hoping I can help keep her spirits up with my positivity.”

Kim found love with Tina Zhu Xi Caruso on “Love on the Spectrum,” though she shared that they broke up last month in an Instagram Story.
