A few weeks ago I told both my sisters that I had been sexually abused by our father as a child. I'm 43 and they are the first people I've told. I was expecting shock but also support and kindness as we are close. They have both told me they don't believe me and I am crazy. I just don't know what to do, really wasn't expecting this and I feel utterly heartbroken and betrayed. My mother died when I was young and am single so they are my only family. Any advice?
