Ohhh, poor, poor Noi :-( !
I wish you and your nose all the best!
The best for you is -I guess- staying at home in bed, don't do too much homework! You're ill!
Take care of you and let your son serve and help you - at least a little bit...
Hope you get sane soon :-)
Drink a lot of warm tea!
Relax and stay calm, better some days off work than weeks more or less ill!
I miss you and your smile
Greetings also to your son
Hope you will soon recover
Wolfram
