What do I do coz everything bad is happening to me?

I'm 16 and i really need help.i am preparing for iit entrance exam and i go to a coaching centre for that.its the best one in my city and i was in the first batch.then yesterday,i came to know that my batch got lowered and well,it really does matter,to me. I've always been a bright student and always at the top.always.i have always in the whole of my entire life been first.and now I've been thrown out from the first batch.and i'm not first anymore.at first it was shock and i was like stunned...it's always been the sun for me.how did it begin to rain?...i never saw it coming.and it's not just rain, it's a storm.my parents took it really well.they encouraged me to keep trying.but i know i've hurt them immensely.i can see it in their eyes...or its probably just me...but i didn't cry at the time until night.all of a sudden it was a snap and it all came out and i cried myself to sleep.today was my first day in the lower batch and we had joint class with my former batch.the earlier batchmates snubbed me.they were condescending probably.or maybe i'm delusional.but yeah i know that this happened because i didn't study and it was so much of underconfidence. i believed that everyone but me is smart. i still do.and i can't take it in anymore.

I'm upset. because my parents didn't scream at me.i want them to. but their encouraging just gives me loads of pain. and then i live in denial. because reality hurts me,i creep away into a perfect world.and now its impossible to come back. and on top of that now i don't feel like studying anymore.it hurts me too much. everything bad is happening to me and i feel utterly helpless, hopeless and crazy. I just can't get professional help coz i can't get my parents into this...

What do I do?
