I also am on the introverted side. I had older sisters as friends but not really the younger group.
When I left, I felt like I could go out and meet lots of people and find friends. I thought extended family who had left, would now bond and be close. Those two things did not happen. So now I am basically alone. I haven't found any group I want to meet up with. There is one or two ladies I chat with at the the thrift stores, my sister, one guy at work, some present JW's at work who pretend that they don't recognize I don't go to meetings and so chat with me.
I end up working and then going home to watch the computer.
