How long have you had social anxiety?

Mine grew gradually.. I was always quiet as a kid, neglected by my parents as the middle, "forgotten" child (they even called me that -__-) and overlooked. I had friends that I was dependant on, I lived in their shadows, and I continued to live in a friend's shadow until 3 years ago. Only then did it hit me really hard, I first realized it when I got around 20% in my english challenge class for being too afraid to hand anything in. I may have always had it, but in a dormant form...just waiting for the solitude to strike.

I've always been shy and sensitive, but I didn't get social phobia until I turned 12.
