You can send it to me and I'll finish it!
I was going to suggest putting it in a closet for a year and then trying again; this has worked for me and it's amazing how much better you get over time, even without taking any classes. But I see that you've tried this already, and it's still frustrating you, so it's time to move on. The next time you take it out to work on it, you will not have good feelings about it.
I would like to say that you've done a wonderful job on the part you did get done; it looks beautiful, lays flat, your points are perfect! Good job! Now go do something you actually enjoy!
