GOLDSMITH offer

Hello everyone! First of all I'm not english so please excuse if I'll do some errors.
So, I applied as most of you for 2019 undergraduate courses. My dream university is Goldsmith, but there's a big problem. I'm not from England and we don't have A grades, in my country universities don't care of your grades but or your real knowledge. I didn't know how important are grades and scores in Uk and this has been the biggest struggle during my current gap year. I scored 75\100 (BBC kind of) at my esame di maturita'. I was having serious illness, i chose the wrong school for me, some teachers hated me without any reasons (we all pass throu it I suppose), I worked bloody hard for my exams and some teachers that really believe in me told me that it was unfair how it all ended up. Goldsmith requires at least 80\100 (BBB level). It's the only university that I care about, the only one in which I want to study. I'm seriously stressed, anxious and depressed about all this things that are completely new to me. Does anyone if goldsmith could show a little bit of flexibility? Did someone has been rejected from Goldsmith? Please let me know a little bit about your experience as I feel completely alone in this situation and a little bit lost.
I'll be incredibly thankful for some help
