Self harm situation

This isn't totally nursing related but I have a 7th grade student who gets upset and then bites herself on her arm. It is a newer thing, I believe, and she states she has never broken the skin. She seems to have a lot going on in her life but she isn't very open to talking about everything. She was seeing a counselor previously but said they just gave her a notebook to draw in when she became upset and that did not help her, she started to cry when talking about her mother (says mother yells at her often) but when she started to tear up she told herself not to cry over and over and then was "fine." She says the only thing she likes to do is sit in a chair and spin, that's all she does at home. Are there any strategies you guys know of that could possibly help? I haven't worked with students like this before. I do not want her self harm to go deeper. She has an independent study to do for class and she wanted to do it on suicide, so that makes me worry a bit.
