Continue study for need some help.

Hello i am Abdullah. I am a diploma engineering student. My dad is a little school teacher. We have 5 brothers and sisters. My two sisters are married. Now we are studying 3 brothers. The elder brother passed the Agricultural Diploma. but he was not getting any job and he too desired his higher education. But he can not take high education for money. And the younger brother will do SSC. On the other hand, Mama needs his medicine all year round. If they do not eat the medicine, they become ill. In such a situation, my father is not possible to run a human being alone. I have been looking for some part time job but it was not possible for the class. I can see that my father is struggling to run my younger brother and his family and I have to spend his money in him. Now it can not be possible for my father to teach me again. But I want to take higher degrees to study. But the money seems to be not possible. My Diploma Course is another 1.5 years left. For this remaining 1.5 years I need more than 75 thousand taka requirements. That is not possible for my father. In this situation, I ask you for a grant. Please help me.
