Hi Olivia
So sorry for what you are going through. I am sure you can get through this stress and come out happier and stronger with your son.
I empathise completely, I'm a mum too with all the stress & complications that brings and I have been waking up the past few months, it has been at times a very painful, lonely process, with days of tears, grief and self-doubt, contemplating divorce etc etc... then there are also days of elation, feeling I'm free of meetings and ministry and all that guilt and judgemental crap. What I have found is it's been easier (for me) to rip the band-aid off and walk away from meetings completely because I couldn't cope with their judgement and lack of genuine care, but I do have family who aren't jws and a close ex-jw friend to talk with, so that might not be the same for you.
Lots of people advise on here reaching out to non witness friends, colleagues, neighbours, family - to build yourself a support network outside the organisation - which is crucial. Also give yourself TLC, rest and take care of yourself, nurture yourself through this time which is recommended in the helpful book Bonnie Zieman's "Exiting the JW Cult: A Healing Handbook for current and former Jehovahs Witnesses" - available on kindle (you don't need a kindle just a kindle app on your tablet/phone). I've also found counselling worthwhile just to have a neutral sounding board to sort out your emotions and clarify your decisions (I had to do it by email because of privacy but it's been surprisingly helpful).
I'm a newbie and there are better qualified members on here I am sure but please PM me anytime I'd love to give a bit of empathy & support if I can. x
