I'm in the same boat as you somewhat
Although i have been able to study, I also feel down. But hey, doesn't everyone? Taking the MCAT is typically not a "fun"experience for anyone. We all have jobs, friends, etc that make it hard to study, but in the end you just have to bear with it and try your best.
Try not to regret ANYTHING that you do. Sure, we all make mistakes, and every one of us would go back and change something from the past.... but try not to think of any procrastinating you have done thus far and look at all the time left.
This brings me to another point.....pretty much everyone writing this test is nervous, etc. But as long as when you leave the test room on Aug 14th you know that you gave it your all, then you really have nothing to regret. Even if you get last place on the MCAT, at least you tried! I can speak fromk experience on this topic...I took the MCAT last aug and sucked.......but there were many positive things that came from the whole thing.... I managed to get a 4.0 GPA this year b/c of it....it motivated me, and made me realize how much I wanted to be a doctor.
In the end look at the MCAT as fate...... if you real;ly want to be a doctor you'll get up and keep trying at this test, right? If not, then deep down you probably didn't want it enough anyways.
All in all, just try your best and relax. Whatever happens, happens...... never look back, and never regret anything. Life is WAY too short to be stressed about this test! One of the saddest things I think I ever read was on this board when some ppl said that the ave SDNer has no friends..... that is such a sad thing! Friends mean so much to me, and without my friends I KNOW I wouldn't be where I am now.....
