Yes, I have been disfellowshipped. In fact it happened when I was 18 and my whole world was wrapped up in the JWs. Going to the meetings were pure torture. My mother saved me a seat in the beginning, but then the elders told her not to do that. It took 11 months for them to reinstate me. And once I was back in, my relationships with my "friends" were NEVER the same. At times I wished I had never gone back.
Some go through the motions to get reinstated and then walk away. I wish I had done that. Instead I jumped back in for 12 years until I faded in my early 30s.
In any event, if you have any friendships with worldly people, please cultivate them now. Try to pull yourself away from the depression of going to meetings to please others. Once you start having more "normal" friendships, it will be easier to pull away.
My heart goes out to you as I know this is very difficult.
