first of all choose your friends if they are kufar stay away from them this is the best decision cause they won't lead u to jannah , understand why ur family is over protective , they care about u deeply , and then about the bf make ur relationship halal , bf _ gf relation ship is haram , and islam have given u the right to reject marriage proposals from someone that u dont like ur family cant force u to marriage that's harram so say no when thye try to force u marry someone u don't like just tell them there is a person u like and u want to marry him
