Could drinking coffee at an early age be a cause for my anxiety?

I started drinking coffee in my childhood. I helped myself when my parents weren't around. I've experienced anxiety since childhood, and I'm pretty sure I have an anxiety disorder of some kind, but I haven't worked up the courage to tell anyone yet. I've heard of caffeine-induced anxiety, and I was just wandering whether exposure to caffeine at such an early age could have played a part in my developing anxiety.
