@jakebe I literally had that happen earlier today. (No worries, I found it immediately and felt kinda silly.)
Interestingly enough, I didn't panic, but merely thought to myself, "Aw, this is gonna suck." I credit a combination of rTMS, meds, and a lot of difficult practice in calming myself.
But I remember well the worse times for my anxiety, and it still comes through in odd ways... like worrying that all of the above will stop working at any moment. :heavysigh:
