Hello Alex.
Thank you for sharing your story. You are right, it's not easy to break free from mental enslavement and those that do, suffer greatly. But more importantly it's having someone to talk to and listen while your feelings are shared.
There are a lot of good people on this board that have gone through the same exact thing as you. You are by no means alone or unique. The WTS has an iron grip on its members not physically but mentally. The mind controls the body so if your mind is enslaved your body merely carries out your mind's desire. It's rather evil what the WTS has done since its inception. I too, like you, sometimes question things like the Adam and Eve narrative. The Noah flood and the killing of innocent babies.
I would definitely advise you to make as many "worldly" friends as possible including those on this board that may live near you. It's incredible to me how blind a person really is when they are mentally enslaved. I, like you, also questioned things like why if the WTS teaches the truth why they would prohibit the reading of material critical of their teachings. Why, if Jesus taught love, patience, and acceptance, are we told in a very generalizing way (propaganda method) that ALL worldly people that do not bow down to them are EVIL. And like you clearly point out, why, if Jesus sat with sinners and even other sinners criticized him for it, does the WTS feel they can impose shunning. This is another matter where the bible contradicts itself. Paul advises brothers to not say hello, eat, or associate with those that profess to be brothers yet are sinners, yet Jesus teaches to "love our neighbor", and how that commandment in itself, everything rested on including all of the prophets of old. So, like you, I truly wonder, who is right. Paul or Jesus. I don't recall seeing in any bible an asterisk next to the word "love" when Jesus spoke of it, to only include those people who were righteous.
I feel your pain brother. Trust me, many of us on this board feel your pain and we are right there with you. Feel free to PM me whenever you need it.
I wish you the very best and stay strong. Yes! Living happy and to the fullest is the best revenge. Enjoy life, enjoy freedom, live, and live well.
