I appreciate you taking the time to write all of this...
You never know when your story will hit the eyes of someone else in a vulnerable position...
All you can do, really, is what is right for you in your own particular place and time...
You mentioned your mother, and how difficult the striking of the balance can be, when your own heart isn't in it, because you simply don't believe anymore...
I wish that I, or someone else here, could simply offer to you the correct steps forward, and that you could proceed from there...
Things here aren't so easy, are they? You seem to be wearing thin from proximity to the JW life...and I understand this well. You see, the JW life taxes your soul, your conscience...and even moreso once you wake up and admit to yourself and others that you simply DON'T BELIEVE...
And as empty as that is, it spells out why such a life is simply not worth it.
Please try, for your own sake, as well as others...to take it all in stride. Sudden moves will have lasting effects that your may later regret. Move toward your goal of fading slowly, and steadily.
Come back here often, for information, or just for support on your journey! We're rooting for you!
