Yeah, and it's OK to feel sad, I'd imagine that's a normal reaction to have in that situation. In my experience it's a rough part of the process of getting back to a better normal. Hope you can get to the better parts sooner than later, stranger :]
Probably calzone? I think a taquito might be sushi according to this
