Kopila Tamang was in Kathmandu when the flooding hit

Kopila Tamang’s family survived the devastating Nepal earthquake in 2015, but their home was destroyed.

This time, the floods took a newly-built house along with 17 members of her family.

“I feel so alone,” Tamang tells CNN. “I feel so lost.”

Tamang – who is from one of the worst-hit areas in Rasuwa – was in Kathmandu when the flooding hit, and rushed back to the mountains when she heard what happened.

The 20-year-old lost her mother, sister and grandmother – along with other relatives including a one-month old nephew. Now, all she has left are the photos of them on her phone.

Her seven-year-old brother is too young to understand what happened, she said, and still believes their mother will return.

“He’s so little,” she said. “He thinks she will come back.”

“Now, I am the mother for him, so I have to be strong,” she said.

Her cousin, 17-year-old Subba Tamang, lost his two little sisters, one-year-old Anjana and five-year-old Archana.

“It’s really hard to believe that I lost my siblings,” he said. “They are buried too young.”

He is now sleeping on a rooftop of an unfinished building in Bidur, with 50 other displaced men and boys.

“Many people cry here at night, remembering their family members,” he said. “It’s very hard to sleep here.”

Along with the overwhelming grief, the displaced families are also living in fear of another flood, and at nights they often flee up higher into the forest when they hear warnings that more floods are coming.
