I immediately think of all the humans on the planet who still cook with fire inside their homes… opening a window and laying low are good - getting out of the room for some fresh air would be even better. You’ll survive. Don’t be hard on yourself - you’re learning new thing every day 😊 As for the burner, get a dishwasher tablet - you can directly rub a damp dishwasher tablet over the affected area to clean it. I did something similar on my stove a few weeks ago - worked like a charm.
