Stressed about life. I do with my life.

I am a 20 year old in inter 2nd year. My mom is narcissistic. She abuses me a lot. I don't know if she loves me or not as she has mixed behavior but the bad behavior is too much. she abuses me for simple things like money for petrol and calls me gay .due to this I have became a selfish person and don't care abt her and my sisters .because I feel that they don't care for me too.due to this situation my relationship with my father has also been broken .he doesnt love me any more.what should I do with my life.i respond to them the way they respond to me. My father thinks I am a selfish and egoistic useless person.he bought me costly bike but he told it was because he wanted to show it to the world and he din't care for me. What should I do.
