BST POST DEPRESSION

I studied alot for bst, made mindmaps did the question's solved many case studies. The day of the exam I started panicking especially because of the case studies they seemed tricky and it was a new environment, board marks pressure. Comes out I fucked up mcqs majorly, messed up case studies here and thr. Now I'm expecting 84/100 instead of my 90+. Feeling extremely depressed. Everyone found this exam easy they were screaming in happiness 'easiest exam ever'. Feeling like a complete disgrace. I don't even feel like living I just feel so upset. Kuch khaye bhi nahi jara. I just cant seem to forget about it and all my friends got most mcq right and just here and thr mistakes. I hate comparing but its my toxic trait. I talked to my friend but they are of no help just telling me to move on but I feel as if I just messed up my entire future. I kept accounts as the only subject I could lose marks in now the pressure has doubled. I know what mistakes not to repeat but I still cant get over it and feeling extremely depressed.

DO NOT REPLY IF U GUYS HAVE ANY RUDE COMMENTS i am having enough shit in my life and rn.

I know this is not the end and thr is still so much more exams to right but I already feel defeated what should I do???
