Hi lovethesun, under the circumstances at the time......." I just walked away to keep from saying something to her that I'd really regret"...........I'd say that you did exactly the right thing!!
Less "beating yourself up", instead try to be real proud of yourself for that!!!
You detached yourself from her unreasonable behaviour towards you, and the risk of it "taking you somewhere you didn't want to go", you didn't get sucked into it. Good on you!!!
Now if you can think of anything you can say to "smooth over" the situation with her, or for next time you see her, assuming she might be calmer then..........then that's great, but if you can't or it's not that kind of a situation hold onto that detachment/of not letting her antagonize negative feelings in yourself as far as you can.......she isn't worth it.
And with that.........any distance you can keep from her, without it impacting on your life, might be good, do you think???

And I may be blowing this so far out of proportion here, and please ignore me if I am........but if you're starting to spot signs of racial harassment there........please be documenting and reporting it, there is never any excuse for that to be happening.
Again, maybe I'm reading far too much into it, but..........
