Welcome, Messy. Yes, I do want to write a book; I'm just writing a bunch of "tracts" here, instead!
I was a wreck when d'f'ed at 15, even though I "decided" I did not want to be a JW anymore and that I was not going to "repent" of that, nor of smoking at the JC mtg. I don't think I ever believed they would follow through with d'f'ing me and then shunning me (forever). Sometimes it's still hard to believe, especially when I think about how young and clueless I was.
I went home after my d'f'ing announcement (the next Thursday, after the JC), and wept all night into my bed, and had to go to school the next day and put up with my family shunning me in my own home until I turned 18 and went to college. Luckily, our relationship was already so shallow, that things were pretty much "back to normal" after the d'f'ing - (shallow, no healthy intimacy, emotional incest, though, little meaningful, appropriate communication) - for the next 25 years, LOL!
I'm pretty sure I developed avoidant personality disorder somewhere along the line, either in early childhood or later, and being a JW did not help. Growing up was horrible and getting out of the house and living on my own has been enormously challenging; like most everyone here, I was just clueless for a really long time; I did not get help from social services for years; I just did not know it applied to me.
Yes, growing up and leaving the borg is messy, but it's worth it. I am very glad I left and never went back and never regretted that, for sure. I just regret that my family is filled with sick @ssholes that I still love, but don't need to be around. It does get easier, though!
