Yup, time to move on. From here, you will just make things worse. Learn from what you did and start a new project from scratch. You will only frustrate yourself trying to work on it any more.
So, Im soooo cracked out on this little project of mine, that Im starting to second guess decisions I made weeks ago... and the bottom line is Im not so sure I can even trust my own ears anymore. What happens next?? Am I done?
