I got sectioned

I got sectioned recently. I was brought to the ER and sectioned there and brought to a psych ward. I was eating my breakfast and a women was singing. I said it was bothering me and she started harassing me. I got up and moved she followed me around the room. Staff just told her to stop then directed me to a table I went and sat there. She came up to me at the table and started in again. I went to leave the room and she started threatening me so I stood up to her. In my opinion the staff failed. They didn’t intervene in a way to stop the women from coming towards me. I felt they didn’t intervene nothing. Am I wrong for being upset? Am I wrong for wanting to leave and asking to because the environment here doesn’t feel safe or therapeutic? I asked to leave and they refused me.
