Another difficult evening waiting outside Callington Tescos for a bus that didn't turn up (it might even have been cancelled, I don't know), and something in the street light above the bus shelter triggered a panic attack.
(Kept hitting my head on the street sign too, which didn't help, though not too hard.)
I had a bit of luck walking back into town later because the bus shelter was open and I was able to sit and wait for the next bus (which thankfully did turn up), and I got home safely. I was lucky also that there were a nice couple of teenage girls in the bus shelter who were able to reassure me that it was the right bus to catch.
