I'm so sorry you are going through all this anxiety and pain. Hopefully one day not one JW you may see on the street or come across on FB will bear any influence upon your life decisions or how you feel. It took me a long time not to care. Nowadays I can go up and say hello to someone I come across whom I recall from my old cong, (I was never baptised, but a born-in), & enjoy watching them squirm as I greet them with a big cheesy smile.
However you choose to make this happen, make sure it is the right way for you. But do it, because allowing others to create such anxiety is awful, I know. I wish you all the best and much courage.
