Breathe....get off the dirt and pull your pants back on. She smacked you good and you responded. You knew it was coming....and backslide a bit. No biggie and definitely not worth beating yourself up over.
How to deal with those situations...Contact Mach, but I will share a quote I remember when assaulted verbally;
Steve: Being called a c******cker isn't personal?
Dalton: No. It's two nouns combined to elicit a prescribed response.
Steve: What if somebody calls my mama a wh***?
Dalton: Is she?
She got her prescribed response....Learn from it so you are prepared to deal with it next time.
Be strong Jfun....The real fun hasn't even started yet and you are doing great.
As for the last line "is she?"......Are you what she said? Think about that one.
