please help me out i reallly need advice and i dont know where to sturn up to

ok so the thing is that i am a Jee aspirant and i am in class 12 now,

the thing is that i have been a really good student for like forever and i got a 93 percent in icsce class 10th

but the thing is that my parents put me in sri chaitanya in class 11 and 12 for coaching to study for jee at first i was happy that i was starting a new life and all but the classes were so hard to cope up with and later on my first year was ruined for jee but my boards went on well i got 93 percent there as well

so in 2nd year i tried to change my habits tried to finish backlogs and all that i was pretty much self motivated and all so i thought it was fine

but now the problem is that i am in 12th and i have barely touched the syllabus for jee i am optimistic but still i get scared a lot

the thing is that i am addicted to watching k drama ,c drama on youtube and just scrolling so everytime i try to study if i dont get it perfect it falls into a routine of that sort

i am really worried i do try to study but i dont know what to do

its that i feel guilty that i wasted a lots of time and i agree but i am still doing the same thing and it takes a toll on me

i got a permission from the principal to takes leaves from college to study at home as long as i show up for the exams , my mom says that i am staying at home too much and says that i am overconfident and this last minute overconfidence will affect my score

i can undertsand my parents worry they are the best parents i could ask for but still

i cant talk to my parents

i can only fix the situation myself
