I feel your pain. I usually just throw my pity party quilts aside for a few days or a week or so until I cool down. Usually I just need time to think of a way to fix it. Most of my pity party quilts are quilts where I deviated for the original pattern or plan and things just aren't working out the way it did in my mind. i have a bad habit of just going with an idea without planning it all the way out.
