Sad story, but hoping for a rise of the fallen

Here goes my very sad but true story - don't worry I will make sure to keep it short and interesting.

Sometime middle of this year - early June - an apparently small GMAT bug bit me. She was invisible, and I did not take her seriously. I thought she was tiny enough to cause me any trouble, and I took it lightly. I gave my 1st practice test and got ~650. With a target of 750 in my mind, I started my journey with the GMAT poison in my blood with a hope that my metabolism will flush this poison out of my body in 1-2 month period.

I started giving my next set of practice tests after a month of prep and was happy to see 680-700 scores. Nice, I said! Let's book a date 1 month from then - I thought. I booked a date for early Aug. I studied for 2-4 hrs on weekdays and 8-10 hrs on weekends, only to realize my score has not improved beyond 700 (me trashing quant and verbal trashing me - that's how we rolled) 8 days before the test. By this time, I had realized that the poison from the apparently small bug has spread everywhere in my body, and I had a feeling it would only get worse.

I decided to postpone my test by a month. Now, I had fully realized GMAT bug that appeared tiny early-on was just an illusion, in-fact she turned out to be a million times scarier than the scariest monster I have every imagined in my widest dreams. GMAT not a joke anymore, and her poison took over my entire life - in-fact she had become my life. She turned out to one of the most high maintenance girlfriend I could hope for, but I had no choice but to keep making love to her from then on. We made love day and night, weekdays and weekends, and at work and at home - I wished I could tell my X what a great time I was having; I am sure she would be jealous.

Two weeks before the test day, we were emotionally attached. She was writing the script for me, and suddenly I realize that I am actually able to satisfy my lust for 750 as I was closing in on 750. GMAT then introduced me with her hot younger sis, and in-fact she let me hit on her sister. I felt as if I scored on the hottest girl on the planet - the GMATPrep. With scores in 720-750 q50-51 v36-40 range 1-3 weeks before the test in MGMATs and GMATPreps, I was getting more and more confident every day. However, I stayed in this range till the end, and closed on a good note in a MGMAT test 5 days before the test.

Something happened suddenly, GMAT started to hate me and made me doubt our relationship in the last week. There was too much emotional drama, only to demotivate me. Not sure why but I started doubting my possibility of closing in on 750 in the real test.

Came the test day - yesterday! My bowel was very angry with me. It forced me to take high dosage of Pepto Bismol. Anyways, I somehow gathered myself together and went for the test in the morning - 1st slot of the day. I took 2 bananas and 1 gatorade with me. Reached 1 hour before the test, and they let me in to the testing room at 7:30 AM.

Came an easy Argument essay! I finished it on time with good revision - hoping 6.0. Came a NASTY FILTHY Issues essay! My stomach started complaining in the mean time. I hated that essay - I always practiced by arguing against the issue in my practice test, but the stupid issue was so biased towards arguing in favor, I had argue in favor. I somehow, with full of disinterest, finished the essay - hoping 4.5-5.0 in that. Well, I believe AWA should be 5.0-5.5 - whatever, who cares? I took a break to calm my angry bowel in the break as quickly as humanly possible. [EDIT: Official report - 5.5]

Now came the Quant - in my lovestory with GMAT, she had always been her softer side. She always gave me love through out my prep without asking too much from me in return. We made lotsa love during the test till 15 mins before the end of the section. THEN A MONSTER - another GMAT taker - ENTERED THE TESTING ROOM. I am sure he was her X. He decided to punish me. His essay section started towards the end of my Quant section. I was at #33 when the beast started typing with FULL NOISE OF THE KEYBOARD, and I lost all my concentration. I could not concentrate well on the last few Quant tough DS questions, and I am sure I lost it there as I remember panicking - scored Q49 (my LEAST of all scores ever).

I took another break, when I calmed my angry bowel again as quickly as humanly possible, gobbled a big bite of banana and sipped a bit of gatorade. Then I came back to the testing room only to realize the monster would be accompanying me during my Verbal section. I started the verbal section, and the guy continued his noisy typing. I could hear everything even with my earplugs on and I COULD NOT CONCENTRATE a bit for more than 70% of the verbal section. I didn't know what I was reading and what I was marking - I was not sure if I should walk outside the room to complain as I was afraid of loosing the precious time. Moreover, my bowel was complaining all the time. The section ended on a terrible note - I knew very well how it went. I was not sure if I should cancel or report the score. I thought f' that, and I reported as I thought at least I would know my worst case in the worst circumstances - scored V22 (btw my diagnostics was just below 30). Total score 590 (q49, v22) - 50+ points below my diagnostics 3 months ago. So the lovestory ended on a sad note, and now I am not sure if should just dump GMAT out of my life or can I actually trust here again.

I am completely devastated with this experience. Three months of hardship has gone in-vain. I had planned to apply in 4-6 top 10 schools this year in Round 2, BUT now I don't know what to do. I have many questions rambling in my head, such as

1. Should I give up this year now, and give GMAT next year? Or, should I give GMAT next month again? I am "sorta" confident that I can score close to 750 "under normal circumstances".
2. What would schools (top 5s) think of my 590, even if I managed to score close to 750 in second attempt? If they are going to look at my 590 and bias their opinion against me, then what's the point of giving GMAT again and wasting my time? I really wanted to start my MBA next year; I have stellar academics and great recos with 5 yrs work-ex lined up. But, NOW I AM DOOMED and feel hopeless!
3. If I give my GMAT end of October, do I still have enough time (2 months) to finish 2-4 applications? How can I give myself a fighting chance this year? Any kind of advice would be much appreciated!
4. How can I keep myself motivated to retake, as I fear that what if something like this happens again?

Looking for honest guidance, advice and motivation. I know there are certain areas I can improve, and perhaps even guarantee 99%ile (under normal circumstances) in my retake in 4-6 weeks.

ps. Sorry if there are typos and grammar errors, as I did not proof read.
