Hello,
I agree with the rest about the chat room; I think having that would be very comforting and nice. The only issue might be moderators (someone to regulate the chat). I donno tho, I think people on here are rather mature. By that, I think if there was to be a chat... it should only be available to registered users.
I belong to another site, which contains a chat room. The site is mainly focused on teenagers and they're personal problems. I know of a few people there who are dealing with anxieties, but not many. Let me know if you want the site name.
