From 680 to even worse 680

Hi, guys! I really need advice here.

So a month ago I took GMAT and got 680 (Q44 V39), I'm not really bad at Quant, I just really do silly mistakes. So I decided to take TTP course for a month to strengthen my Quant and I really liked the course and I did start feeling more confident about it as well. I finished all the sections, did lots of practice in TTP (not all questions though, but a lot). I bought GMAC Exam 3&4 and scored Q46 and Q49 respectively (absolutely identical to exam conditions, at Q49 even finished 10 minutes earlier). Since I really only need 700+ and I never scored below V38 in my Verbal, I decided I was ready to give it a go. A couple of days ago I took another GMAT test (a month apart from my first test) and scored 680 again, but this time - Q42 V41. Despite my very active Quant preparation with TTP, I scored even lower than I did on my first exam. That day my exam was after lunch and because of my daughter I only had 3 or 4 hours of sleep at night. On my way to exam I spilt my coffee all over me and my documents, so this added anxiety. But my confidence is shattered. Although I'm from underrepresented pull of candidates, I really feel I need this 700. I have almost perfect GPA, but I finished my BSc in Econ and Finance 5 years ago, so this is a lot of time without studying. I promise, I'm not stupid, I just can't seem to have cracked what it takes. I have no idea how to proceed, I'm not ready to give up just yet.

What do I do next? How do I proceed? Was it just anxiety? Should I give up? And also, I ran out of Verbal practice questions (whatever you have here, I did, including LSAT and everything). I always start with Quant during exam, it helps me to warm up my mind for Verbal (lol), but maybe I should try Verbal first? How do you guys decide for yourself? So, you are great at all this, any advice is greatly appreciated. My third exam date is Aug 12 and I'm miserable. I only need about Q46-47, yet somehow I feel as a loser. With my Verbal increase, even if I did my Quant just as bad as I did the first time, I would have gotten 700. But it is what it is. So guys, here is my miserable story, I'm ready to hear your verdict.
