Never enough

I got 60% in my chem mock im in year13 and I worked so hard i literally went to my teacher everyday for chemistry and asked her for help or like where i was going wrong. I made sure I understood everything and then this friend revised 2 hours the day before and got 61% . I feel so stupid bc i put so much work in and for nothing, i worked so hard only to get an average grade, it took me weeks to understand something which somebody else understood in two hours. And you don’t understand she knew NOTHING a few days before the exam and she skyves her lessons.

Ive also got a really bad homelife and have always craved academic attention and try my best to be “likeable” and then theres people that dont even try and are loved. It’s really started to affect me bc I feel like i’ll never be enough, i’ll never be enough for my parents or teachers and im basically a failure
