There's not a thing wrong with you. A lot of people hide who they really are when they interact with others, mostly for all of the reasons you listed above. No one really gets me, except the people online and my sister, and that is enough for me. And so I don't worry about it. Sometimes I do put myself into situations where someone says something that makes me uncomfortable, but I tend to keep my distance from people like that anyway so it only bothers me for a moment and I shrug it off immediately. You're not alone, not by a long shot. And really, there's nothing wrong with who you are. Nothing at all. *hugs*
