Nightmare came true - Scored a 650 - Way forward?

Background

I started preparing for GMAT in June using the following materials:

1. Official Prep (OG + Review + Practice Questions)
2. Power Score CR
3. Manhattan SC

Following were my official mock scores:

PT1 20/06:660 (Q49,V31) (no prep)
PT2 09/07:690 (Q49,V34)
PT5 25/08:660 (Q50,V29)
PT6 31/09:720 (Q50,V37)
PT3 09/09:710 (Q51,V35)

As I scored 710-720 in mocks (Extremely similar testing environment), I booked the test date for a week later. I thought I was hitting my peak last week and was confident of getting a score above 700.

The Nightmare

I wont lie, I was crazy nervous on the test day. Three months of prep and having a lot riding on the exam definitely weighed on me. Moreover, being aware of the horrible drops in scores from practice tests to official GMAT for a number members of this forum, made me more cautious. Nevertheless, I tried to be as cool and calm as possible and started the test.

As I was comfortable in quant, I started with verbal first, maintaining the pattern in which I took my official mocks. During the Verbal section, I thought I was getting difficult questions, which made me happy thinking that I was doing well. But in my attempt to get some difficult questions right, I lost track of time, leaving me only 10-11 minutes for the final 9 questions.

I somehow scraped through and closed the verbal section by guessing the last three questions. Thereafter, I took my break, relaxed and started the quant section. I read the first question on Time speed and distance, a type of question which I have probably practiced more than 100 times, and got right more than 95% of the time. I formed the equation of the question and BANG, I completely froze. Crushed and unable to do very simple math like 30/8 in my head I was completely blank and helpless, sinking under the weight of a ticking clock and the depraved rhetoric - 'I have practiced this so many times, I will be able to solve this'. The next thing I know, 6 minutes have passed without me answering even one question. Still, I tried to hold myself together and power through the remaining paper. I somehow reached a comfortable position, and had 17 minutes for the last 10 questions. Though I completed the questions, I was not happy with the fact that I had to rush through the latter questions in both sections.

After finishing IR and AWA, reality kicked in. I scored a dismal 650 (Q49, V31), which was lower than my lowest mock. I was disappointed but was expecting such a bad result. I knew that the sins I committed during early parts of the exam would come back to haunt me, and they certainly did. Moreover, I understood that the verbal questions I deemed difficult, were actually medium or easy level questions.

I have attached my ESR, which certainly indicates how bad I performed in the final quarter of both Verbal and Quant. Although I am disappointed, my ESR has given me some good insights about my weaknesses.

Way Forward and guidance

I plan to take a break of a week or two before resuming my preparation. In the meantime it would be great if someone can have a look at my ESR and point out the things which I can improve on. I want to analyze my performance asap as the test taking experience is still fresh in my mind.

Thanks,
