If your Dad set up a trust and the will was probated then you still have an insterest in his estate. A living will and power of attorney are only while the person is alive. A legal will handles the estate of the deceased.
To contest the PA of your sisters regarding your mother means going to court with proof that she was diagnosed prior to the signing. I'd file a complaint with the License Board of your state on the attorney who should have known full well that she was incapcitated and the matter needed to go to court or at least have all people with interest in the matter present and their input.
To deny you access to your mother, your sisters would have to prove that you would harm her.
It is a tragedy that occurs in way to many families when parents age. If they had known of the animosity that would result, they would have taken better care to avoid it.
