Time was of no consequence as she lay on the couch, only getting up to occasionally use the bathroom. Harry had left the other couch hours ago, or was it days? She no longer cared. She existed and that was it, she heard Neville when he told Harry he was beginning to worry about her and so she cast another  muffliato  under her blanket and screamed until her throat bled, the taste of blood gave her mind something to cling to, a new sensation to grasp at. The blackness stole her once more and she sighed with relief as it encased her, she was drowning but she couldn't find it in herself to swim to the surface.
