Help for medical treatment

My name is Anik Roy. I am 22 years old I am a student. I am a 3rd year student of the Department of Accountingand Science . I am working as a teacher in a private coaching center. I earn 120$ month from this coaching center. In my family, I have two younger brothers and sisters. . My father died two years ago and I have an old mother in my house. My family ran very hard with the money of our earning. My dream was to do good for the country with higher education, but my dream broke. Last night on 28-2-2019 at around 8pm, I lost my left foot after a slight road collapsed under the bus. And my dear friend with me died on the spot and some people around the place took us to the hospital, then The doctor declared dead to my friend and continued to follow me, when my family and relatives came, at that time the doctor said that my legs were cut We need to have an appetite but at that time we did not have money, then my operation became friendly. After 2/3 days, the help of Atiyasan and the people of the area get help of 80 thousand rupees. Then there was my little operation in which I did not endanger my danger. The doctor said that the foot should be taken out, because the entire rate of the foot has fallen behind the bus, so the legs should be cut off. The operation requires about 8000$-9500$to successfully. It will take so much money, because the feet will be cut and cut. It is not possible for me or my family to do so. It is very expensive. Where do I get so much money? Besides, it is very difficult for me to run a family and run medical expenses. Please help me all by thinking of me.
