I'm thinking of the scars on her arm
Why are you thinking about the scars on her arm?
She usually wear gloves and long sleeves so I'm just surprised
If you see someone has been self harming themselves then you should ask them why. It's good to also get them the professional help they need.
My sister self harm herself and I just want to know why she does it. I'm just trying to protect her.
It's good that you would want to protect your sister like that. I hope you're able to get to the bottom of it. If you ever need a hand talking to her please let me know.
