@Roberta,
(((((Boida)))))), I'm so sorry that it didn't go as it should have done and that you have to carry the unknowing around in your head after being so mucked about.
I hope you are feeling a little stronger today and have warmed through and that you can get a new date soonest and have the biopsy, though I get that you need to organise your thoughts first.
I'm just so sorry you have to continue thinking about it and have to gear yourself up to go through it again.
Help from the taxi-stranger, bless that taxi driver for getting you home and out of the cold when you needed it the most.
Snarl for a bit, then perhaps use the energy you have to book the new appointment. Hang in there, Boida. I do hope you slept some and feel better today. Keep warm, eat soup, feel hugged. X
