Medical Cost for friend’s family

I'm going to start a fundraising for my friend's family:

1. Father: He is living in Dhaka, Bangladesh. His name is Sahadat Karim Khan, 76 Years old. He is blind for last 3 years. He has also blood pressure, diabetes, skin irritations. He lost his wife on 2019

2. Son: Ehsanul Karim Khan, 49 years old. He lost his job for Covid-19 pandemic. He suffers bone injury for dozen years ago in case of playing cricket. He is almost handicapped for that. He needs surgery soon.

3. Daughter: Rezwana Karim, 42 years old. Suffering from uterus tumors.

They're conditions are terrible now. I helped them as much as I can. But now, it's quite hard for me to contribute more with my limited income.

I will be very grateful to you people if you help this family to live better.
