I do hope you feel a lot better today. It has been more than a week. I would say, calm down and face yourself. I bet you studied hard. AUD was a hard part for me. My first language is not English. So for me, I tried to remember as much as I could. There are things which are not hard to understand, but whether you can remember them and turn them to be part of your own knowledge is another thing. Hopefully, this helps.
