what can i do to be happy ?

I have a boyfriend and only I m 16 years old. I m Haitian .so do my family . I really like the guy and he likes me too . my boyfriend and I are waiting until I m 17 close to 18 to talk to them about me . they saw his messages on my phone and they ask me who was that . I can't lie for something like because I don't want them to see me kissing him on the street and take me for a nobody. So I said yes that he loves me and I do too blablabla... So now my uncle is mad at me so do my mom , grandmother and aunt because they wanted me to have a boyfriend after college or almost done with college . my school let us go at 3:15 most of the time but I go home at 4 sometimes I miss my bus I arrive at 5 . I was playing with my friend , I didn't pay attention to the time , I arrived at 6. They think everyday I go in his house . like the freak is this . The things is now the say I m Haitian I m supposed to wait for 20 something to have one but I get it but not my heart. I m avoiding them . one second I m down stair and next second the just don't see.
