I feel socially awkward a lot of the time. I think I've lost my social skills because I don't go out much at all, and when I do it's just with my mum, so I'm never speaking to other people.

I've recently come back to this site and it's taking a while to get back in the swing of talking to people. I do go in the chat room and I can relate to what you said - when I first join the room I feel a bit nervous because I'm worried I can't join the conversation or think of anything interesting to say.
Everyone on this site is so friendly though, and when you're in the chat room people try to involve you.. it's a really nice chat room here
