Jourles, your courage & experience and your mother's response is a defeat for the WTBTS's mind-control techniques.
Out of sight out of mind let's a parent who's shunning their child off the hook emotionally to a great extent, but when they're confronted by that lost child, the dark evil and inhumanity of the shunning & abandonment is overwhelmed by the greatest force in the world - love!
Parents who deny their parenthood when face-face with their offspring in such a situation, either consciously or sub-consciously must seriously detest what they have done, and continue to do.
I hope you can reunite with your mother soon.
