Hi I’m sorry to hear about what happened. I pass out quite often (in comparison to everyone I know) and I have panic attacks aswell due to my anxiety, so in exams I get moved to the back of the hall (seated behind everyone else) just incase something happens. But I’ve found that since moving to the back my anxiety levels are a lot less, I feel really panicky when I’m surrounded my lots of people I found that this really helped! Also when I’m stressed I feel like I can breathe a bit easier. I haven’t actually passed out in an exam, although I almost have several times so I really understand how horrible it feels. But I think it’s down to the exam board, maybe have a look on their website and see if they say anything about it ! X
