It sounds like you have a good basis for some lawsuits (and criminal charges if you can convince someone), hopefully at least one of which will be financially worth it. Of course you need to gather good evidence first. Consult with a lawyer first.
That sucks though.
There is an entire "targetted individual" community on the internet.
You can tell that something has happened to them, but its ephemeral, because its psychological, and what do all of us do when we don't understand someone ?
We dismiss them. We other them. We isolate them. We walk away.
Not as a group decision, but the outcome of our collective individual decisions.
Abuse someone long enough, psychologically, and if they are not educated and self-aware, their behavior becomes erratic and they lose all social support.
It's not unlike veterans of a war, who understand what each other went through, when the public doesn't.
