Well done for going back to class, it's so easy to try to avoid it to 'catch up with the loss' but in reality most people are just hurting themselves by not biting the bullet.
More often than not when i think i have been really bad ive actually been a lot better than i use to be, theres things you learn on SW that you never forget and find yourself sub-conciously making the right choices, so you may be pleasently suprised that its not as much of a gain as you think.
If it is what you are expecting then that's okay, you have had your blow out, draw a line under it and start again.
Good luck tonight
