Poor Countess.
That's a frazzled immune system that is.
A poor diet and a broken up routine (seems normal now) - a different toothbrush and a different glass of water (seems normal now) to wash her mouth out every night.
Rather than multiple sexy encounters as she wanders the highways and byways, hither and yon...
Much more stressed than you think you are - and subsequently behave in the company others - young lady.
IMO opinion that is.
Just eat an entire jar of Marmite and you'll be OK.
Or something.
