I definitely feel your pain. I'm waiting patiently for my results for what I hope to be the last frickin time I ever have to do this. Although every time I take this test, I learn a little more. I recommend that you jump back into studying as soon as you can stand it. The diagnostic report should show you where your weakest areas are, and you can start on those areas with plenty of time to work on them. The longer you wait, the longer it takes to get back to where you were the last time you took the test. You will pass it if you study. I believe this even though I don't have my results yet. Check back with me in a few days when I have received my results, and I'll probably have some colorful things to say about it one way or the other.
Once you pass it, and if you keep trying you will pass it, it won't matter if you ever failed it. Don't let it get you down. Go have fun for about a week and then when you get your diagnostic report, pick up where you left off in April. I'll look for your name on the top of the screen some time next Christmas.
