Why do you care so much about what other people think and says?
There is no way that you can stop them, so forget and ignore them
for your own sake.
Don't you have better things to do...like cheering yourself up
instead of worrying about breaking some nonsense school record. To
hell with their records, you don't even need to care if any of them
goes to the toilet on time or not.
Think about the available options that you can still take if it is
really true. Spend a lot of time thinking on how to prevent this
kind of situation from happening again. Failing sucks...but if you
really tried and still failed, then you shouldn't feel too bad
about it unless there is something that you could have done to
prevent it.
Remember, exams isn't everything there is to life. There are more
crazy and tougher situations in store for you in the future. So
please ignore the people around you and what they do and think
unless you are in control of your life right now. I hope that you
can forget/forgive/ignore them and yourself and give yourself
another chance. I'm sure everything will be alright the next time
around, don't you think so? 
Good luck.
