I know. My family was the same way. Here's what I did.
First thing i did....I distanced myself. First thing you need to do is tell your mom, "Mom, I understand what you're telling me; but right now, let's please not discuss anything religion-related. Just be my mom. I need some time." Tell her in a mature adult fashion (since parents have a hard time sometimes regarding us as adults with our own thoughts). It took my mother 4 years before she and i could have a relationship - but it also took me being a bitch and putting my foot down and telling her I'M DIFFERENT AND NO LONGER BELIEVE WHAT YOU BELIEVE. I had to finally tell her one day, "Mom, you raised me to believe the WT. I am now an adult and choose to disagree. I will respect that you believe it to be true and will not try to convince you otherwise. However, I wish you to afford me the same respect."
Which was difficult for her to swallow. After all, my family had a "reputation". we were the model family in the congregation. Grandpa was in the Yearbook for his pioneering work in South America...yada yada yada..... We reached the point where she disowned me. it was difficult....and i too had to take antidepressants. Felt suicidal. Felt alone. Disowned by family and had newborn twins, and a 6 year old, and had just left my JW husband. All my uncles were elders.....aunts pioneers. I was being groomed to go to bethel and got married instead! So i know what you mean by the pressure. If they are inundating you with emails....store them in a folder for now and read them later. YOU have the power to read them when YOU want......and if you're not in the mood to deal with it....then delete them or save them for later when you DO feel ready. But your hubby has a point. You will need to be the one to put the brakes on and request that they respect your decision.
then go get a hug from hubby. Email anytime you wanna chat. I know what you're going thru. I was alone for a long time. But the saying is really true....all this you're going thru will make you a stronger person.
