Yo,

I have a mock exam today which is last thing,however I woke up at midnight and began throwing up and I feel so sick. I am already skipping one lesson this morning because I keep being sick, I have to go in for second period as I have to attend this talk thing then choose my courses for my second year which will be the same as this years. 

However between that period and the mock I have lunch and a study break that adds up to just over 2 hours, I don't know whether to ask to take the test next week or just fight through my vomiting...

I know my teacher will be happy for me to take the test next week as a few students already have to...but one side of me wants to get it all over with but I have a 3hour exam tomorrow starting at 8:30am and I want to sleep this sickness off. 

Do you think I should allow myself to rest and be prepared for a real exam tomorrow and ask to take my mock next week or just fight through vomiting...
