She is utterly over-reacting. If there is no underlying condition or worry that is causing her reaction (ask her), it might be over.
I'd have a heart to heart with her, be honest and, if no resolution, take a step back and see if she gets it and tries to make amends.
The trouble with doing nothig and ignoring it, is that it will still stick in your craw I think? And she might think unreasonable behaviour is ok if aimed at you.
