Afraid

I'm at the beginning of my semester for Spring 2011. However, I'm more than uneasy about it and I can't shake... I'm afraid, why am I afraid of this success. I have the goals I need and I'm ready to start... I just have this huge fear. Do I fear the failure? No, I've failed in the past... I've also succeeded too. What is this feeling and why can't I shake it? Hopefully, I'll easy my worries tomorrow when I crank out some homework.
