anxiety attack!!!

god i m suffering from anxiety attack from like what yesterday
i cant sleep early to prep for my paper the next day as a result i was a bit tired to do my math paper today and that result in a shitty performance seriously that paper was do-able but i m under superbly stress condition when i was doing the math paper
even before the paper my heart cant stop beating furiously fast
it is funny coz the first week of prelims i was calm and i manage to do most of the first week papers maybe an exception for maths paper1..
yes math has become a huge barrier to boost my confidence
even my dad says if u dun have the confidence to do the paper there is no way u can get a good grades
with that i become more stress!!!!! i cant find that spot in my soul where it is all calm and quiet and at peace
my soul is having a war now!! it is a toatal chaos in me!! ERGHGHGHGHGHGH!!!!!!!!!!!!!
during srtessful papers my mind will always wonder i will keep asking myself if my friend will be able to do the paper well and yeah that pushes me on to solve the qns but i m not at a calm mode so it is not that helpful either
why!!! i m feeling so nervous!! tomorrow is physics paper2 and i hope i can bring it!!
i know that i have to do well
ergh RUZ!!! stop it just calm urself down and do ur best!! like what u have always said just give in ur 110 percent and at the end of the day it is up to the judges to fail you or pass you u know u have put in ur very best to study and really understand the concepts dun have to worry what happen later just do the god damn paper with a calm soul will you!!
