There's a lot of talk about cyber bullying with regard to children and teens (which is very important), but I never hear much about bullying adults. A year ago I had a breakdown because I was being harassed and bullied on a Facebook group. It was one of the most awful experiences of my life. There weren't any resources to turn to for help.
I'm very sorry that you've been victimized in such a cruel way. No one should experience cyber bullying.
