Atheist...

I am 25 and i'm student in MA. My life is a bit different from that of my friends and of my society. I was born where traditions and religion play a heavy duty role in the everyday life of everyone(but in fact they are just lying at themselves, because none is faithfull), in fact i hate my life coz i'm different, i dont believe in what they believe in and i have been lying at them for many years. i dont believe in God coz i'm an academic..i'm trying to convince them the importance of self-estimations and interpersonal qualities but none has listened, they say that religion is the priority, I'm not sure that something like that exists (my personal viewpoint coz i have been doubting God existence for many years and what i got are always negative answears)..I've lied at my friends and my familly and i'm still lying.. I dont know what really have to do.. They won't understand me if i confess.. I'm extremely bound to what they practice.... What shall i do?
