First, I don't think that we should treat stats with so much respect - there are numerous instances here where people have studied for 7 months to 1.5 years, toiled at it and emerged victorious. So, I don't think your hard work can ever be your undoing.
Second, I think your score is nothing to get too panicked about. You have around 10 days to cram before G-day and have identified your main weakness - SC. I would suggest that you go through the MGMAT SC
book, cover to cover, again and download the various SC guides and practice problems available on this forum - the SC guide by whiplash, SC guides by Gayathri and Spidey, the Brutal SC question set and the Brutal SC solution thread available on this forum. Doing the 70-odd problems of the Brutal SC set and going through the solution threads should give you confidence and improve your SC.
Also, although your main focus will be SC, keep spending 50% time on the other areas (quants and verbals) as well.
Meanwhile, I would suggest that you take 2, possibly 3, full time mock tests in these 10 days as well - I believe GMAT test taking practice is important - it's like jogging 2 hours before a marathon.
Once you are done taking GMATPrep2, reinstall the GMATPrep software and take both GMATPrep1 and GMATPrep2 again given the question bank is huge and the repeats should be few.
Give it a shot - try to take the GMAT as another test (I know it's easier said than done, but you can try:)) and always know that you have another shot, and more to spare!
