Dear Yuying,
First of all, thanks for your sharing!
I'm glad to learn that you are ready for another fight! Don't ever lose confidence in yourself. When I decided to retake GMAT after my interview with Emory, I wrote to my interviewer and told her my decision. Here is her response:
Thank you for letting me know of your decision to retake the GMAT - this shows strong character and a
willingness to "do what it takes" to succeed!
I wanna share this with you and all of the test retakers. Wish you guys good luck!
Do feel free to let me know if I can be of any help!
