Is there anything that I can do or not do that could maybe prevent the
worse from happening to yet another family, this time mine? I've
already been greatly helped through this all these months by reading
this forum. Thank you for listening.
Yes, go back. Seriously, return to attend meetings.
I think the way you are fading is a little too rushed and impulsive. Fading is not just stopping going to meetings. All the things that you posted should have been taken into consideration first, before taking any actions. Fading is a process that requires a lot of decision making and thinking about all the consequences (like straining your relationship with your father) as well as all the things that you will have to deal with and are willing to give up.
As a born in, I understand not having a reliable frame of reference about the world outside. It's fundamental to start getting to know what you are getting into by coming into "the world". If you are a born in, trust me, chances are that you have a rather naive, tunnel vision view of how the world is and works. The process of fading also involves preparing yourself to what you will be facing once out, especially when/if once bad things happen to you. Life brings challenges and those challenges may make you question your decision of leaving.
Furthermore, leaving all your family and all you have known all your life is going to bring you down. Have you prepared to deal with the emotional toll that it may take?
You don't mention anything about your reasons for leaving or what exactly triggered your decision,and it's important for you to look at what are the reasons why you are willing to walk away from everything and everybody that you grew up with.
Fading and leaving is a process; it takes time, planning and preparation, especially if you want to maintain a workable relationship with JWs you love and are still in. I strongly suggest to maintain the hypocritical charade and pretending to care while you build support outside, learn more about what your life will be once leaving, and keep yourself in the life of those you love.
It's not an easy process, so just stopping attending meetings may be a little drastic.
Go back, return to meetings for the time being, is my suggestion.
