Miss.Fit, what a nightmare! Have you had professional counseling? You're no longer a JW, are you?
What you have bee through is inexcusable. You and your siblings should contact an attorney and sue the FP's. I don't know how old you are or how long ago all of this happened, but it sounds as though you really have a case.
Meanwhile, be thankful you survived, and build the best life you can for yourself. Living well is the best revenge, truly.
