Hope that you could read another post from a new member,

I feel it too, it's the feeling that you know you won't fit in with them and those people would look at you like:" do I know you?" or "he/she is strange..." or even "what a weirdo..." But in the same time you are desperate to talk to someone, at least someone that understands you.

What I did was to select carefully my listener. I'm a nerdy and geeky type so those who are the same are my first choice. I tend to approach them individually so they would be concerned with ME rather than other people. Then I try to show my best interest in my favorite topics, making the conversation interesting.

I do hope that helps
