Thank you @raspberrytorte and @Blueberrybook for your well wishes

The technique my T suggested is kind of like exposure therapy where you get used to something a little bit each time you are exposed to it (like crowds, heights, etc). So it'll take a while to start working but there's a bit of progress each time.

I tried the technique yesterday - it was my first try but it seemed to help reframe the source of my anxiety. Of course I was still anxious but I had another way of looking at why I was anxious in the first place.
