Your mother needs to get the message that this mess is her doing and she needs to fix it.
She raised you in a doomsday church that already had a string of prophetic failures before you were even born, (name one that occured in her lifetime, that she would have had to ignore, excuse, whatever). Jehovah had steadfastly refused to do anything the WT promised on his behalf before you were born and she still gambled on them, a high stakes gambol that if Jehovah let them down as usual could easily result in her kids leaving the church, resulting in instructions from her church leaders to shun them if they got DF/DA.
It was her choice to raise you in the church, her choice to advise you to get baptised even though Jehovah had already clearly demonstrated he didn't support the WT's promises, and now it is her choice whether, or not, to attempt to call the dogs off and try to influence them to leave well enough alone ..... and if they do announce you as DF/DA it will be her choice whether, or not, she lets her church leaders tell her to destroy her relationship with you.
