I think there might be a few bugs going round. Where I am, there's a normal fluey one - aches & pains etc, and also a tummy one and a more head coldy kind of one.
You're just reeeeaallly lucky, girl!!
You might be a bit run down?
I haven't had a good flu yet. I escaped unharmed last year, so hopefully I will this year too.
Poor you having to go to work tho, that's the worst. Rest up when you can & drink lots of water.
(((big hugs))) hope you are feeling better asap.
