Hi Tami, I'm sorry to hear your awful story. As an ex-elder in the UK who heard of a few cases of child abuse in my vicinity it was men or older teenage boys who committed abuse. As more and more news articles of JW abuse have come to the fore I have heard of rarer cases where women were abusers too.
To have your own mother abuse your own children is probably among the sickest of the sick as far as paedophilia can go - my heart goes out to you.
You have true friends here. Please stay.
