Can I Get an Answer?

My questions are these: I have 13 brothers and sisters on record and a total of 15 of which I am aware. There are two more paternal siblings here in CA. So, why have I only heard from "Nicole", who resides in Canada? Nearly forty-one years have passed and only one of my siblings will reach out. How difficult is it to acknowledge your brother?

Initially, and as it turned out, forevermore, my father refused to acknowledge my existence and ever favor me with his love or presence. And now my siblings are perpetuating the same. I have been trying to figure this out since I was 7 years of age. What did I do to deserve this level of abandonment? Do any of you value family? Is it because I am in CA? Is it my criminal background? How can all of you be so ruthless? How am I different than any of you? Are all of you going to go to your graves stuck in the same stubbornness that dad did?
