Answer:
She may be suffering from child abuse, or some other type of harassment. I'm not sure the steps because I'm not in the same school course you are, but for sure you would need to tell the teacher or some authorities about your concerns.
The reason I think she may be suffering from child abuse is because she held her arm stiffly, it may have been broken. and she wore a hoodie.
I believe the first thing to do would be to befriend her. This is because you would need to pick her brain and see the things she may be going through on a day to day. It may be abuse, it may be depression. Self harm can be one of the reasons why she might want to cover up. The first step would be to befriend her, then if having trouble talk to a teacher and get advice.
