I want to be a better christian and earn god's love i need someone's help he hates me?

i have been raised in the church but latelky i have done some bad things. i have stolen and robbed people. i also cheated on my girlfriend with her best friend. i don't know satan has really been working within me lately. i masturbate a lot also and look at porn all the time... i'm really worried i'm going to hell and i don't want that. i have been pratying to god and jesus and the ghost but they won't listen to me or answer me, and i don't think they love me anymore. my mom found out about some of the sinful stuiff i've done lately and basically told me i'm to pack my bags and get the hell out and find somewhere else to live... but where will i go? i guess i could move in with my girlfriernd's ex-best friend but things have been awjward with her lately. i don;'t know i really want a drink and a smoke right now but i know that's wrong and will damn me more to hell and stan has just been really mean and tough to me lately and i don't know maybe i'm a satanist and heathen and i feel god wll never forgive me now and that he hates me since he won't talk to me at all i'm really scared please tell me how to be better and get back to his love
