Yes, I have pretty-much always felt like an outsider too although it is true that, in my case, I probably made myself an outsider as much as other people made me feel like one. I've never really gotten along with people for the most part in real life. Nowadays I just keep to myself. So it's no longer an issue for me. But then I'm old. So being a recluse works.

I'm sorry you are feeling like an outsider. As Teddy Bear rightly observed though, you're not an outsider here, which is I suppose why a lot of us are here on PC. Because here... none of us are outsiders. I wish you well...
