Welcome breakingfree!
So glad you joined us! As I'm sure you have read, there are many, many here in the same boat as you; you are not alone. And most gratefully, you will find excellent advice from your "new brotherhood" when asked.
I am from the camp of "less is best" as regards any communication with the congregation or CO. I wasn't on JWD when I left, I didn't have my answers sorted out when I faded, and had to go on my instinct. I used personal health and circumstances, which were truthful, to successfully avoid confrontation. By laying low, it took a while for the news to reach relatives and friends which gave me the time to be sure of my decisions.
As far as the family is concerned, I've avoided all discussions of my new found truth. I put myself in their shoes and know I would defend the WBTS to the death if I was in that mindset. So I'm of the opinion that unless one is searching or questioning, it does no good. And I feel if they are questioning, they will be able to find what they need to start their journey on the "dreaded" internet.
Remember, anything you say cannot be taken back. And once it is relayed from person to person, through time, as will happen, it will not resemble anything you originally said in the first place. To my very best g/f who is in, I have said over and over to her "I have issues with the corporation, not the congregation." And she doesn't ask, and I don't tell unless I'm asked.
I wish you strength for the journey, and again, "welcome" to JWD.
