Hey everyone! Im an INFJ but can relate to a lot of what is said here. I prefer being around smaller groups and tend to handle it better. As for larger groups I guess its hit and miss, sometimes i feel comfortable and other times I question myself why the hell did I show up to this group event! Anyways a while back I found this website
PersonalityCafe
The website is all about the different personality types from Myers Briggs. Scroll halfway down the page and youll see each personality has its own forum for discussion.
