My family is like an evil, wat shall I do???

I have ped my 12th dis year n wanna go in some engineering col out of jaipur coz dere r no gud col here, bt my family wants me to either drop or do BTech frm jaipur as i did nt got selectd in aieee or iit. I also hv one more xam of amity bt if i did clear it den i il hv to live in jpr. But I noe if live here den I il nt be able to live my life as I want, coz my family does nt give my ne freedom n restricts me frm doing nethin n also abuses me a times fr very small mistakes, n also treats me like an animal a times. They all r devils, actually i live in a joint family, they always criticise me n never ever praises me nt even for a gud work done by me. I shall rather kill myself instead of livin wid such a family. I m gonna try it today coz m nt goin to live wid such a family.
