How old is she? Sometimes the suicidal thing is just a phase. It was with me as a teen. My parents paid it no mind. Found my death notes and everything. Cutting is just a phase too but can become addictive. I dont have that issue anymore but when I was a teen it felt like the only way I could cry.My niece too. I'm not sure about the gloves but she wears a mask at home and stays in her room when her brother is home because she is afraid he will give it to her because he sometimes takes his mask off when he plays sports. She is sixteen.
She is suicidal much of the time and her first counseling appointment is still a few months out. She's been waiting for it for many months already.
Thankfully, her mother works from home. Which keeps her safer but it is also really rough on her mother because her mother is the safest venting target for her.
