Welcome TITS! It's always great to see you. ;-)
I started working my way out when I was a teenager. I'd seen a lot of bad things happen as a JW. Some were in the congregation, but most happened to my family. I thought there was no point in worshipping a god who had repeatedly failed me. But my mother was an active Dub, so there was no way to get out of the meetings. She ruled the house, iron-fist-in-a-velvet-glove style.
I did a slow fade by getting more involved with school. Fortunately for me, my whole family has always valued education, so there were no objections. I also go t a job, which no one could object to because we were pretty poor. I would spend 9 - 12 hours a day at school, then work after school and on the weekends. There was no time for meetings when I was spending so many hours out of the house.
I was finally able to do a clean break once I went to college. My mother didn't accept it, and still doesn't, so we have a pretty crappy relationship.
Be glad that you have your immediate family on your side. Yes, losing your JW friends would be hard, but losing your family is much harder. It's a lot easier to make new friends than to make a new family. Besides, the majority of kids raised as JWs will leave the religion. (The JWs don't advertise it, but the only way they keep butts in the seats is by constantly getting new converts.) You may meet up with your friends later in life as ex-JWs.
