Having a cold

I have had a cold, it lasted a week and I was so very grumpy about it.
I'm not good when I have a cold, it irritates me so much. I get angry and I feel very sorry for myself.
I am good at tumours and cancer... well so far
but a cold, useless.
It's to do with feeling my energy is being wasted and my time is better spent recovering from when I'm really poorly.
