Help for Ulcer Treatment of my younger sister and save her life

My sister Amena Akter is 17 years old student of Intermediate last year at Konabari Degree College in Gazipur ,Dhaka. After two months she will attend to Final exam 2018.

Unfortunately she is attacked by Peptic Ulcer. She is now under medical treatment in Crescent Gastro-Liver Hospital, pantha path, Dhaka and now fighting with Peptic Ulcer. The Doctor prescribed for surgery immediately to live her life. We are not capable to bear the full Surgery cost. The cost will approximately $16000 . And we collect $4000.

Please give your helpful hand to my sister treatment so that she will recover from Peptic Ulcer and go back to her college.
