Her elders told her that im "causing the family suffering, a clear
sign how leaving Jehovah breaks up families". She's also destroyed all
photo's of me (including baby photos).
wow.. that's pretty far out.
You might not want to hear this, but perhaps it's time to let go. Destroying baby photos of you practically means she has completely lost it. There is only so much worth, in family ties.
When a friend tells you that he does not want to be friends with you, best thing to do is comply and cut ties.
Likewise, your mother is telling you that she does not want to be your mother. It's rough, but there is a life out there to live.
