Please help me…

I'm studying computer science and engineering(CSE) in a private university.I has admitted there last year.Actually my father did not want to admit me in a private university because his income is very poor but because of my tie, he was forced to get me admitted there.I am leaving my family and studying from a low quality house.I have a younger brother and a elder sister,they are both students.In this situation, it has almost impossible for my father to spend our studies.On the other hand, my sister's marriage is almost over but my father could not give her a marriage.There are seven members in our family.So if you help me, it would have benefited me, my father and my family.
