Oh dear, that's terrible! No matter what you do, you should give her a good shouting-at, for good measure. I'm sure it can't be within the boundaries of the law either, what she did, but it's true that you might regret taking it to court after all.
In any case, I hope you'll let her know how pissed you are at her ^^'
And I hope you do find a place to sleep...gawd, but I hope you do.
Also, that art is awesome.
