There's nothing wrong with you - if you dislike making conversation and pointless chit-chat, don't. Ignore anyone who says you 'need' to be more sociable, you don't. Simple as that. If you're only worried about this because of what society expects, shrug it off. I'm assuming this is the case from "All this isn't really a problem for me, but I realise that it's going to be a problem for everyone else".
If, however, you WANT to become more sociable, just act interested in what people say and try to be attentive.
If you're happy the way you are, there's no problem to solve.
In summary, fear of not being accepted is for little emo weiners, and you don't want to be one of those.
