I was an above average student with score till 11th i scored 86% in 11th. But achnak thi, in 12th standard because of my family problems, parents ke bich ka problems, break up and soo much more including financial Condition! It started to feel stressed and frustrated and because of all of this, not giving any importance to health I suffered physical and mental health problems! I have failed almost all exams and I am right now in very below average college that I don't even want to go! I want another chance but nobody is believing me and feel extremely demotivated!
