I feel your pain! Last month, I took, what I thought, was a half-done disappearing nine patch to a retreat. I was very confident I would be done within a day, and be able to move on with something else. I had such a hard time, cutting and turning and making sashing, that I finally gave up after working on it most of the weekend. Last night, I pulled it out and everything looked so easy. I don't know what my problem was expect maybe overload.
