Xhud gaye guru

I started my prep in 12th only this year in may from allen i studied only ncert syllabus in class 11 when i started my jee prep i didn't understood anything in class i just used go go class and make notes but slowly slowly i came on track and finished my 12 syllabus and then in September i started 11 too from Arjuna batch. In morning i used to study 12 in coaching and in night i studied 11 from pw and now my whole physics is completed and chem almost too but maths is fcked .. ik many people don't do this syllabus even after studying from 2-3 years and i did all this in spare of 8 months even with good amount of questions practice.. but i am thinking what if i didn't get good marks (below 150) then what will be the use of all this i have done in 8 months .. i used to sleep for 1 day in every 2 days fcked my life so badly in 1 room never step a foot outside but after all this if i don't get result then idk what will happen to me and because of all this thinking i am not able to study properly from last some days and this is most crucial time what should i do 😭
