Hello,
I know exactly how you feel. Just a bit more than a month ago, I took the GMAT for the 2nd time and scored 640 (q47,v31).
Today, I took it for the 3rd time and I got exactly the same total score 640, but with a q42, v35 split. I do admit that I spent most of the time over the last month finishing up stuff at work and also trying to finish the verbal questions in the OG 12 + Verbal review.
I think the main downfall was that I spent the last 3 days with a fever. Either way, 640 is enough for the schools I want to go to, so I should focus on the applications now. I'm going to have to find something else to fill the void of studying for the GMAT.
