Anyone please?

So i just wrote my math final exam today and it went terribly wrong
originally this year government reduced our lessons because of lockdown but my school kept the whole syllabus and the whole year was online expect the final and during the end chapters my network was horrible
I wrote what i could today i guess i will just get 40 out of 80 i am disgusted by myself i just hate myself
Idk i am just super sad my day is terrible so does anyone have anything that can cheer me up please
I would be glad ╥﹏╥
