How many people don't talk to there imediate family- Mom Dad Sibblings?

Im in my late 20's and this past year my family and I have feuded over underlining past issues-my parents divorced when I was 8, I've always felt like a guest at my fathers house since my step mother hates me she's known me since I was 8 and my father always teams up w/her and never sides with me. My mother is insane and has not been a mother to me for a long time, My step father hit on me when i was 18 I didn't do anything he liked me, my mother divorced him and I know deep inside she hates me and blames me for her un happiness we don't get along, I have a little brother 13 he lives with his father my ex step dad so I don't see him often, also my mother gets very jealous of our relationship and tries to turn him against me. I feel so alone with out family i hate mine, and I chose not to speak to them is that wrong? Whats your story please respond ONLY id you don't talk to your family.
