I’m kinda confused. If she doesn’t help, then why does she herself want guardianship? Even if you DID need help (which you obviously don’t), I don’t see how she is even fit to be one. She has not demonstrated anything.

Sorry that your sister is doing this. It’s cruel and disheartening. Best of luck at your pretrial. It sounds like you’re gonna win this one (as you should). Hopefully she backs off when she loses.
