Got 680(Q42,V41) !Clueless!

Firstly,i would like to thank gmatclub,bunuel,bb,souvik,vercules,and many others who have replied to my queries all the time.
I had my GMAT today and got a disappointing 680.But,am still ok for what possibilities it holds for me.I wouldnt comment on GMAT strategies because i don't consider my score to have met my expectations
Still,i would like to share my experience at the test centre today:

I booked an 8 am slot and being a morning person,i found it okay to give GMAT early in the morning.All set to give the exam,i experienced some nervousness,and sailed through AWA just in time.
IR went Okay,but wasted a lot of time in first question(went blank).Gathered my self and took a break after IR.
Quant started at an easy note and some easy questions popped out,surprising me and making me suspicious of my calculations.Still,i remained calm and started double checking my answers and was pretty confident.Except for one answer where i just clicked the wrong button and repented just after hitting yes,but otherwise i thought it went well.(Only to discover later that quant made a hole in my score ) I have been scoring 48-49 in all my pracs so i was expecting a 48 here too.
Anyways,i started verbal on a positive note that if am able to beat it,i will be done.Questions popped,difficult ones,but i managed to glide.RC was tricky,but i did okay,i guess.I took a lot of time i guess,coz when i looked randomly at the timer,and calculated my time lag,i was shocked.I was running 4 questions behind as per the time.I lost confidence and felt upset.Started rushing through RC passage,but tried making educated guesses,speeding up my thinking process.Ran through lot of questions,biggest mistake.ADVICE: Never fall in comfort zone,as soon as you feel its okay to take time,and you are going ok,just gather urself up and maintain the resolve that u have to be decently fast.Anyways,luckily, i knew that i ws ok,not great as the questions seemed to make sense,and somehow i regained time.last question,1 minute and i was done.
Felt sad bat verbak but thought that quant would compensate for the damage.
and whoops,score presents a different story altogether!!
Anyways, i would just like to say that never get disappointed by your practise scores,(like i did in verbal ,only to realise later that i did perform okay,which i think is good ) be positive every moment during the exam,you never know,and be sure that you do your best in time crunch(in case you fal short of time!)

Dont know if i will give another attempt,but right now kind of broken!
