I looked on your blog at the 2009 quilts and here is what I saw.
1. They are beautiful
2. They are not simple no brainer quilts
3. You have very high expectations of yourself.
How long did you crawl before you walked? How long did you walk before you could run? Did you fall down while learning?
Quilting is like life, you take what it throws at you, learn from it and keep plugging along.
There is nothing wrong with you, you just got stuck in the sand. So here is my suggestion. Make a very simple quilt, not too big, and sandwich it by basting with very long stitches. Put it in a round hoop and hand quilt it. This will relax and de-stress you and get you ready to take on the world again.
You will win
