depressed af and need helf to focus again

studied nearly 3 years daily cutoff all friends all hobbies for jee. now i am slowly losing my santity as the days pass .ever since i was a child i have been treated as this prodogy miracle boy and that pressure has eaten my soul. i dont know what i will do if i am not able to get an iit. not happy with my mains percentile (99.72) even if everyone tells me you achived something extraordinary i feel hollow. i lost my spark my curiosity and am a shadow of my former self. i didnt have my rank back then but had my happiness. now i dont know anyone , dont have any friends no hobbies. everyone says people would die for a rank like this you should be greatful but i feel nothing. dont know what to do dont know what to study dont have any more motivation left in me to study even if i really want to push my self to my mind cant take it anymore. all i have ever wished for is an iit no matter what branch or college and i feel it slipping away. so yeah any suggestions to gain my focus back or something
