Thank you all for your kind words and comments!
The heat was fixed late that evening, and I ended up sleeping over at that friend's place. I did not feel like going out again late at night in the freezing temps.
In general I am doing better, though I am struggling with some insomnia. If it is not one thing than it is the other...
This upcoming Monday I have the biopsy for the thyroid nodule scheduled. I am trying really hard not to freak out completely about it. I am not scared of the biopsy itself, just the results. I really do not want another surgery.
