Has anyone been disowned by their entire family? I have and it is the MOST punishing thing I can imagine.?

For 5 years, no one in my family has spoken a word to me. There was no "Incident" or Event that initiated their silence towards me. My mother is behind it. She's a sociopath and has always been very jealous of me so much so that she literally wants me dead. I have been destroyed by being "Erased" by my family. I still don't know why, other than the fact that my mom has done a wicked PR job of slandering me to my relatives. I have written to them, literally BEGGING them to tell me what I did to make them hate me, but in 5 years, no one has ever responded to my inqueries. There aren't many books written about true DISOWNMENT. If you know of any, please let me know? I feel so alone -- because I am!
