Hi, I'm a never-jw (some family in, and "studied" for a few months), but I am a mum. You are exactly right to put your welfare first now, and that of your children, born and not born.
Unfortunately, in my experience jws are trained to detect and exploit vulnerability (after all, it's for our own good right? ). But, it's great that your family have decided to ease off.
Best to avoid discussion of things jw until you are sure you're ready. Don't hesitate to say you're not ready, have a headache, backache, need some space, whatever. Practice some "gentle put-offs" - any counsellor could coach you - such as "I'll consider that when I'm feeling better", "no, not right now, thanks", "tell me about . . .(anything else)" etc.
And keep doing whatever makes you feel good now - spending time with your kid is great; that's the sort of thing you'll remember in the better times to come.
Best wishes, Retro
