I've been the same over Christmas and New Year, now fighting to get them back under control as i'm mostly recovered. I was vomiting everything i ate from 23rd - 25th December, and i've had no appetite at all after that until New Year. Bloods are still high and i'm still coughing a bit but miles better than i was. I wouldn't worry too much about high bloods when you're ill, it is perfectly normal
get well soon! Keep drinking lots of water and try plenty of vitamins - fresh orange, while very high in sugar generally helps me recover quickly
