I haven't read this whole thread, so if I'm repeating thoughts covered, sorry.
First off, that was very brave. It's going to be so great to be open and honest about yourself from here on. It sucks having to cover up all the time. Make up stories and then have people also guessing and rumors going around. Kind of like when I faded and had to pretend I was still faithful to JW rules & restrictions. You had the bravery I didn't to tell your family the truth. And unfortunately at the cost of family that I didn't pay.
I wish you the best in this. Not sure where you live, but if you are near any large city, there will probably be gay support groups and a gay community sypathetic to what you're going through. The family shunning thing isn't uniquely JW. And if you're part of a gay community of friends, you will find others that can tell you the same thing. Especially if you live in the more religious, close-minded parts of the country.
On the postive side, being openly gay in today's non-JW world is going to be easier for you than many who came out in the past. Attitudes are changing.
I know all of this doesn't help with your family. Some of the gay people I know have had to turn their backs on family and move on to happier lives.
