I understand what you are saying. I used to be really afraid to start any quilt because I was afraid I wouldn't like it when it was done. I spent too much time agonizing over the pattern, the fabric, you name it. I have only recently begun to realize that the world won't end if I make a quilt that I don't like, and I CAN stop in the middle of a quilt if I know I am never going to like it.
I am still working on this. The quilt top I finished two days ago made me so happy because the picture I had on my "mental design wall" matched what I ended up with, and I loved it. So....I started planning my next quilt, experimented with numerous fabrics, none of which went with my focus fabric. Finally I accepted I wasn't going to like anything I was thinking of and made a tote bag out of my focus fabric...a tote bag that I really like.
I just read over this, and now I think none of this will help you. Perhaps though, you can realize that "the world won't end" if you make something you don't actually like. Just finish it or put it aside, and go on to something else.
Sewing up a kit, as others have suggested, may be just right for you now.
Good luck. You will work through this, I just know it.
