You said that even typing about Aspergers is making you hyperventilate, which I assume means you think it is a bad thing. If she is diagnosed with Aspergers, it's not a new thing, it's something that she has always had which just stayed under the radar. It opens up new oprotunitys, and gives you an explanation for some old behaviors and issues. It would help you deal with some of her issues better, and will give you a better idea of what to watch out for in the future. Aspergers is not the end of the world, it's a new beggining.
