Feelings are feelings and you are entitled to feel what you feel. I’d be very unhappy being interrupted by a brother walking taking that’s just a no no. Going to ER or urgent care for her daughter who could possibly have cracked skull is a different story. Is daughter having some other issues? Why did she fall? Even if she stayed in a session she’d likely be unable to focus anyways. I totally get how you feel but I can’t imagine doing anything knowing what’s happening. I get it about being professional but life happens. I do understand though if emergencies happen a lot then maybe you do need a different t. With no kids. But she might have elderly parents etc maybe the one who does therapy in the office not at home.
