Please help family and religious issues Christians only plz?

alright i no this is long but please read. ever since i was five i have been surrounded by death. i had to watch my great grandmother die at age five because i couldn't go anywhere else. i never knew my great grandpa or gradfather. my grandmother and grandfather on the other side of the family hate me because i listen to metal, they think im an evil. so just recently i transferred to a christian school. i had a girlfriend for the first 10 months i attended there. then all the sudden my friends stab me in the back and now even the teachers hate me. and to beat it all i told my ex (while we were dating) that i have land (which i do as a promised inheritance from my dad) and now my parents hate me. now my slutty sister is the favorite. so now everyone hates me and i began to go in a downward spiral. i have sinned, and the addiction for lust has consumed me. i can feel Satan's tightening grip every day. like for no reason ill want to go emo or run away and all that stuff. i resist but it is getting harder. i have cried out to god but nothing.... i ask for forgiveness and my guilt consumes me. please help me i am begging you. i am on my last leg here and i am on the brink of a mental breakdown. to top it all off whenever i do something like when i go hiking and i start a campfire my dad freaks out and stresses like a woman, this isn't a very manly figure. now i don't even have a grandfather to go to because of family disputes. WHAT DO I DO. i am at a fork in the road and i need help, please.
