Hi M.,
IMHO I wouldn't color it OR bleach it anymore yourself. If you bleach it one more time and you're hair is already chemically damaged you could wind up with hair that is so over processed that it will turn to mush. I've seen this happen and there is no fixing it when it gets to that point. If you color it to try to cover up the blue and it's the wrong shade of red it may end up purple and then the stylist will have a lot to do to try to correct the 2 different colors. My suggestion would be to live with the blue hair for a while or get in to see your stylist before Thanksgiving. And please let the professionals take on coloring your hair in the future :) In the long run it could end up costing a fortune to get a color correction versus a color or retouch.
Good Luck!
