Central Board Of Secondary Education [CBSE] — Regarding 12th result

My name is Anshika jain class 12th from HOPE ACADEMY SCHOOL TIKAMGARH M.P. I have been in top position in my class 11th and 12th preboards, still I got 72% and some of my classmates who were lower than me got 80% above percentages . School faculty members are accepting their mistake but not doing anything. They ruined my future now you tell me SHOULD I COMMIT SUICIDE??
