There will always be people that are like you in some way, dont worry. I remember I felt I was the only one that still plays pokemon, and then I discovered that there are a lot and lots of people who play it. Be patient, and most importantly, be optimistic. If you think negatively, it will feed bad thoughts about the other people and it will cause you to withdraw more, and so on.
I'd recommend to at least try to communicate with the other groups? Tell them you want to learn their language, and that you can teach them. Who knows, you can form a very strong bond!
