considering you are in india I did some googling... the heirarchy of family is different in india than here in america, the father or other adult male in charge of the familyis the all decision and controller in the family. that means your father according to india's laws is well with in his rights as head of household to treat those with in the household as he sees fit in order to keep the family in control, disciplined and socially acceptable. in other words india goes according to a "caste system"

based on this I would not be able to say its right or wrong whats going on in your family, how you need to do this or that....

what I can say is that if this continues to bother you maybe you can sit down with your father and explain how getting through your schooling will actually benefit the family and what ever "caste" your family is. how your schooling will help you to help profide financially for you and your family.... you know add all the good points you can that will bring health well being and good reputations, socially and economically acceptable .... you know all that stuff that is the reason behind why your father has allowed you to gain a higher education for... maybe having a conversation with him that isnt going to belittle his manhood, reputation and as financial supporter of the family will help him to understand you need his help. maybe even offer to help out with your siblings more so that your father wont have to keep such a firm hold with everyone.

and lastly if things get too bad in your household there is help India Help Hotlines, Helplines & Suicide Lifelines for Kids, Teens & Women. they will be able to help figure out what to do next in a way that wont cause harm to you and your family members because of going against the head of household (father)
