lol I grew up very much alone with few friends. My bother and sister are older and we were home schooled and went to a church with almost no other kids most of the time, so I learned to be alone and didn't relate well to people my age. I always tended to have more in common with adults. I started dating my wife in my teens, and I guess she helped pull me out of my shell and got me into a group of friends, so I developed pretty good social skills over time, moreso later as an adult. But most of our friendships have fizzled, people moved away, had kids etc and we don't, so we just don't socialize much. I also have some hearing loss which makes it very difficult to interact in a Crowd. And I also find people today just talk over you and its very hard to get a word in, and they pay little attention. So I just tune most of it out and withdraw. On here you have time to have a back and forth, and you have time to think if what to say as opposed to being in person lol.
I'm sorry though about your family. I'm blessed to have pretty good relationships with most of my family, so it's strained with my sister and her family.
