There's a lot of assumption that she was cutting herself. If someone is at genuine risk of self harm by cutting, tell me - would that person be permitted to have a sharp knife about their person to cut up their apples with? Would they be issued with standard stainless steel cutlery? This inpatient was, and I never once saw her attempt anything inappropriate with them.
She did however take offence at being asked to turn her music down. So she ate several bags of crisp, biscuits and drank milkshake before inducing repeated vomiting by sticking her fingers down her throat. She then proceeded to lie down and pick the vomit bowl up, deliberately pouring it over her face, before pressing her call bell and fake choking on her own vomit (having quickly thrown the empty sick bowl under the bed first to hide the evidence).
Thankfully, an earlier nurse hadn't shut her curtains fully at one end, thus affording me a clear view of the whole shit show from my bed opposite. I gladly informed the nursing staff what had actually happened, and I was spat at for my troubles.
I'm truly sorry for your trauma, but honestly you are giving a benefit of the doubt to someone who massively doesn't warrant it.
