you are not alone..... I'm sure they are many others dealing with similar issues but don't have the courage to let it out...... I'm glad that you did...... I'm sure not being understood from the one's that your very close to makes it difficult... however, I'm sure you Might have heard nothing is impossible.... this is feeling is temporary...... it's not going to stay with you forever so dwelling in it will not benifit you or anyone around you.... no one but only you can get your self out of this miserable state that you have got yourself in..... stress is pretty common but useless and waste of time...... instead of you participating in it, participate in things that you should and make the situation better for yourself..... why stress? if you can work it out and if you can't, why stress? don't be fearful..... just do you, give your best and you will witness things falling in place for yourself..... never let yourself down...... you more capable than what you think you are!!

you know just last year I was in 9 grade and I was going from so much and parents didn't understood I was going to fail badly and seeing my dad trying to tell me that you leave this and study and all my mum always had that disappointed looks or she would scold me that how waste my time . I have social anxiety nobody knew about it and when I told them no reaction.so my mum started my tution and I wasn't able to take it it was online when the first session ended I walked normally but when I reached the bathroom I slumped down I cried. and well this didn't had a happy ending do fast so,..............I failed total 3 subjects I was horrified wasn't able to take pressure again I had to retest that s the good part I got passed by .5s (I cannot suddenly be a genius).well I think they don't understand it rightnow too. do what maybe if you have a school counselor get some sessions so she can conclude or get a good website in which there's symptoms and everything WhatsApp them maybe that can help. good luck for your exam.
