Believe it or not but a long long time ago I was in a shell too. Painfully shy. As Frank Ze says sometimes it's necessary. Perhaps. But perhaps it will never disappear. You find a way to deal with it. My shyness was (is) a combination between very low self esteem and not understanding 'others'. I walked around constantly asking myself 'WTF am I doing here'? The moment I realized that I couldn't go on like that, I think I was about 13 or 14, I thought by myself: Okay I'm never ever going to be a model, so I need to be smart and funny. I started reading ... a lot. Up will now I have a ridiculous huge level of curiosity. Curiosity killed the cat? Perhaps.
