to expect some sympathy when I'm feeling really rotten but haven't got any visible symptoms?

[DaphneHarvey]

Had splitting headache for 4 days.

No energy. No appetite.

But no cold or sore throat, no stomach problems, just feeling like I can't DO anything. Utterly washed out.

DH at home today, I went back to bed for 2 hours this morning (utterly unheard of, don't think I've ever done it before since having DCs).

DH huffing and puffing around the house like its a terrible inconvenience.

Perhaps there's nothing wrong with me?

Are you me?
Luckily DH came home and did the washing up, and we cooked together. I bet you are fighting off a virus. I do wonder if it becomes a bit of a vicious circle though - feel rubbish, eat comfort food, stay indoors more and don't get out walking, therefore feel rubbish.

Sounds like you could be coming down with something. Try drinking loads of water and getting plenty of fresh air.

Hope you feel better soon x
