Need money For my Father's Heart Surgery

Hi Guys! I am 23 years old. I live with my father.  He is a heart patient. There is a vein which is blocked. Due to medicines that he used he got other side effects like hearing problem. The inner part of his valve is swollen and it is getting thick day by day. Medicines have slowed down the growth of the valves but it can only be stopped by treatment. My father has got premature retirement from a firm. We have no money.  Doctors are demanding for 5,000$. I am a student and it will take me to complete 1 year in bachelors. We are living from hand to mouth. Need help. Hurry! Please
