I'm sorry you had such a bad day yesterday. I know I've had a few myself - it's had to make the test your priority when there you have so many things going on at once. Glad you're over the hump, now get motivated and get your score way up!!!
The bibles should help you quite a bit, but have you considered tutoring? Not sure if it's an option for you, I know it's definitely not in my budget, but a tutor could help you identify the mistakes you're making without even noticing that you're making those mistakes. I would go through the bibles first, and gage your improvement, but that may be something to look into.
Also, I know some large schools have tutors and LSAT programs available to students and alumni - maybe yours does too? They offer discounted rates and lots of materials for free. You don't have to be a pre-law major for it or anything, just a student at the university.
Maybe take a day or two off work and devote them exclusively to LSAT prep to get you motivated? You could probably work through most of the Games Bible in those two days, and it would make a tremedous impact on your scores and your mood
