I am sorry you feel that way. I am taking the exam the very last day. I am still studying for it and exhausted, but this is the home stretch, so here goes everything. As a repeat test taker I can tell you, first of all, congratulate yourself on making the decision of going for it again. Yes, you can decide to put it off for later, however I'm not sure if that would have been counter producing, especially since you have the knowledge still fresh in your mind.
Second: Take a break!! you don't have the results yet, and there is nothing you can do about it until they are released, so for now, don't go back to study for it. Put your study materials in a safe place and leave them there.
About those who are asking if you can find a job without the boards, the answer is yes, there are options. I am not recommending to anyone to not take it obviously, because I will be taking it in a couple of weeks, but this is not the end of the world. Just be honest when you apply and go with your gut feeling. Why would someone want to work with a bunch of snobs who make you feel down if you repeated a test. Yes, the offer may be more tempting, but it does not men the work is better. And yes, before anyone tries to explain how things are in the real world, I know that having the boards is preferable when you apply for all the reasons behind it (hospital bylaws, insurances, etc). In the end it is only an exam and it does not mean that ANYONE is stupid or makes you a better doctor just by passing. I now a few who have passed and couldn't take care of any patient. There are others that last year were freaking out and soling their pants only to find out they passed and now are acting as if they are superior, HA!
I will let you know when I take it. May need moral support as well...Who knows?
