Urgh I hate the flu! Kelza has given some good advice. Might also be good to make sure you use either hand gel or antibacterial hand wash before and after doing the hammy food (if it smells strong wait a few minutes for the smell to go!)
Get plenty of rest, keep your fluids up to stay hydrated. Maybe take some paracetamol or Lemsip (but not together as Lemsip has paracetamol in it!). I hope you feel better soon
Though its always a good excuse to stay in bed or stay in yohr pajamas
