I'm sick and tired of always being sick and tired

I've been in bed since Friday afternoon (Sunday as write this) and just mustered the strength to blip the carnage I left on the floor as I shivered my way in. Christ knows what is wrong. I was ill a couple of weeks ago and then got better and now it's hellish again. Splitting headache, sore muscles, coughing like a geriatric who's smoked 40 a day all his life, blocked nose, weak and miserable. I don't know if it's the air quality, the biting cold, eating food from street vendors or the general state of disarray my flatmate leaves the kitchen in (man, I miss having my own place). Anyway I'm pilled up again and hoping I'll be fit to go back to work on the 26th. Tidings of comfort and joy be upon you all.
