3rd paper khatam kiya aur panic attack aaya, parents ko samajh nahi aa raha 😭 koi genuine solution do please!

literally just finished my 3rd paper and i feel like crying. my heart was racing so bad during the exam i thought i was gonna pass out. like i knew the answers but my brain just went blank. kept scratching my palms and couldn't breathe properly. my mom called me after and said "tumhe toh roz exam dena hai, kya problem hai" and i just hung up. they think i'm doing this for attention. i tried telling them it's a panic attack but they said "bas natak hai, padhai pe focus karo". so triggering yaar.

i've been trying this breathing thing my friend suggested—4 seconds inhale, hold for 7, exhale for 8. it helps a little but not enough. also started taking magnesium supplements but idk if that's actually working or placebo lol.

honestly i'm so tired of feeling like this. does anyone else get panic attacks specifically during exams? how do you handle the pressure when your parents don't even believe you? koi genuine advice please. i can't keep failing my papers because of this.
