i can't do this anymore

wht do you mean it's cityworks from glasgow colleges 

They have some good priced anxiety books on Amazon.

Try not to panic ok, you got this. Just need to calm down and take some time to breathe. An anxiety help book is a good way to go, I own a few and they're really useful.

First thing foreigners find out after coming to UK is that english don't speak language they've been thaught to be english. Next is that every city speaks different language

Most Foreigners learn English through US TV. So, they all speak with US accents, and expect us to talk slower. 

Rant over. 

ahhh they teach english to foreigners wrong anyway, they do it overly formal and it just doesnt fit with reality and common english, which is why we often get alot of foreigners trying to correct native english peoples english and tell us were using it wrong when its literally our language and we are using in naturally... so education yet again proves that it fails anyway here again lol i wouldnt worry too much about exams or education as education is a joke these days anyway.

Given your timeframe, maybe a book is best deferred for now in favour of meditation videos on YouTube. Something that can calm you down over twenty minutes, get you in a better headspace, give you some breathing room.
