Thanks everyone and Gabe, I have lots of whiteness too. The tidying up sounds good but biopsies are such fateful little monsters. I don't know if it's wimpishness or a vivid imagination that makes us fret before anything bad has actually happened! Maybe it's the lack of control: someone else has our future in a test tube ...
I've just told my school that I won't be back next year. Living with this uncertainty plus an unwell husband plus the stresses of teaching at 65 ... Time I retired anyway. Proud I taught for a whole year with half a tongue.
And yes, I'm certainly going to escape somewhere this week for some personal thinking time. I have to prepare for the worst and think of a whole lot of points of clarification if this is yet another false alarm.
