How do I overcome my fear of creating artwork?

I recently recieved my scores from an A.P. exam for art, where i send in a huge amount of artwork and a panel of judges looks them over. I can get a score between 1-5, 1 being the worst and 5 being the best. I got a score of 2. It was a massive dissapointment because I worked harder than anyone else in my art class. I spent every moment I had at home, at school, and weekends to generate the best quality artwork I could give. Apparently it wasnt enough. Now I found myself avoiding my art desk, although knowing that if I do not draw again soon, I will be out of practice and I will have to work really hard to get back to where I was. Its been over 2 weeks since getting the letter, and I've been trying to force myself to get back to it but then I find an excuse to sidetrack...What should I do? I really need help. How do I overcome my fear of creating artwork?
I have just the opposite problem, I recently finished a masterpiece, according to me and all who have seen it, but am afraid to go back to the table due to possible disappointment I will not do better.





So, all we can do is try and practice: remember we can always erase what we do not like and rip up what we despise in art. As I tell my small son now, never be afraid to erase son, if we didn't no one would ever finish a piece.
