Creative blockage

I recently decided to focus on being creative and feeding that part of my life. I set up time to create, I started thinking about myself more as a "creative," I signed up for group Life Coaching with a creative life coach. And what happens? I can't seem to create much of anything. I feel like a complete fraud. The last few days I have this sinking feeling that I am not really creative and that i just **wish** that I were creative. I sit down in front on my computer to work on some designs that have been living in my head for awhile, and what happens? Not much...mostly just crap that some 1o-year old would make during craft time at summer camp. I started on a painting and was digging how it was coming along...then tonight I went over and ended up complete f*cking it up! I am going to have to start over from scratch. And this is not a "oh, you can fix it?" or "who's to say it is a mistake" sort of thing...it's a completely, totally, non-redeemable action. Ughhh! Maybe I should resign myself to the apparent fact that I not actually creative and clear out all of this stuff that clutter up my craft room.
