A Greek heiress was found dead inside her England apartment after being discharged from a hospital over a troublesome insect bite, according to reports.

Marissa Laimou, 30, was discovered dead in her London apartment by a family friend last Thursday shortly after seeking medical help for an insect bite, according to Greek outlet Parapolitika.

"She was bitten by an insect, she was itchy, she went to the doctor, she took antibiotics, she ate, she slept and she never woke up," Laimou's mother, Bessie, revealed to the outlet

"My girl left for nothing," the grieving mother said.

Laimou, an heiress of a prominent Greek shipping dynasty, had also recently beaten a breast cancer diagnosis, her family said.

"My daughter was saved from cancer. My little child," Bessie said, calling her daughter a "diamond."

Laimou began to feel unwell after being bitten by an insect on Sept. 9 after returning home to London from a vacation in Greece, family members told the Daily Mail.

It is not clear what type of insect caused Laimou's ailment.

She called an ambulance after experiencing troubling dizziness, itching, and a high fever, but decided to stay home and seek medical attention the next day if she still felt unwell instead of going to the hospital, the outlet reported.

The next morning, she rushed herself to the "Leaders in Oncology Care" in London, where she had previously been treated for chemotherapy.

While there, she was treated with antibiotics and antihistamines. The oncologists then decided to send her to the University College London Hospital due to her worsening condition, the outlet said.

At the hospital, her family alleged nurses, rather than doctors, carried out tests on her and ultimately decided to discharge her.

She went home, went to sleep that night and never woke up, family members said.

A family member confirmed to the outlet that the dynasty plans to take action against the doctors who discharged her.

"They are going to go against them of course. This is 100% negligence. Marissa is gone because of them," the unidentified family member said.

Laimou was born and raised in London and moved to the United States in high school. Upon arriving in the US, she studied at the New York Film Academy for one year and received a bachelor's degree in Musical Theatre at the University of Arizona, according to a casting call.

She returned to London in 2018 to continue a theater career, earning a role as Juliet in a production of "Romeo and Juliet."

"The entire family is shocked by the sudden death of the daughter of Diamantis and Bessie Laimos," her great-aunt Chrysanthi Laimos told Parapolitika.

"She was a very kind girl, quiet, educated, cultured, modest and simple. She loved art and theater, she was involved in theater. Warm condolences to the family! Strength and courage!"
