Very first thing is to walk away from it! To keep trying to push through will simply upset you more and get you more frustrated. We all have a project (or two) that is sitting in a box because it stopped being fun and became a real chore. Once you have taken a bit of time, then go back to it. From your pictures, it is not that bad. A quilt is supposed to be 'bubbly' and even some of that might be pressed flat if you desire. NEVER RUBBISH BIN A QUILT! There are so very many people who would treasure a handmade quilt. If you are concerned about giving it as a gift to someone you know, donate it. BTW - I think it looks fine, your piecing is great, your points are wonderful. You have put a lot of work into it.
