i'm not gonna make it.

i'm 24 M, still living with parents, trying to get degree (if everything goes right i will graduate in 2026). The problem is Tomorrow is RRB JE cbt 1 exam. AND I DON'T REMEMBER ANYTHING . Literally i spent last 9 months preparing 6 months with dedication, sacrificed my sleep, missed marriages of homies, girl asked me for date, told her to wait one year she didn't. . i knew i was dumb but didn't knew that im that dumb. i mean thats the reason i started so early. . due to lack of sleep my face is swollen, my eyes are sunken, my professors think i started drinking. . i can't disappoint my father no more man, im done. this is as long as it gets, if i fail im done. I can't face him. Im getting panic attacks just by imagining all this.
