going insane

I cant stop thinking abt my score and the many different possibilities. I genuinely have no idea what I did on any of my exams except bio and psychology which I’m pretty confident abt but other than that no clue and I’m freaking out , i was predicted a 43 and i for sure know that i won’t reach it hell I won’t even get a 40 but I’m just so stressed bcs i have to reach certain requirements for uni

is anyone else stressed?
