Storyline

Hey guys, I'm starting a manga, just for myself. So, there's a character named Maria in this, and she's VERY mentally unstable (DID, bipolar, sociopathic, borderline, paranoid, schizophrenic). She also self-harms. So are there any creative ways for her to injure herself, for the story (She's an artist)?
Thanks,
Kiseki.
