Hey there,

I think that it would be okay to talk to your friend about this. You can ensure her that the reason you heard it was completely accidental since you were in the same room rather than because you were eavesdropping, if that makes you feel better.

But, if you talk to her, maybe you can let her know that you really are worried about her. Let her know how much you care about her and tell her that if she ever needs someone to talk to about what is going on, that she can come to you and you will listen to her.

You can also let her know that self harm doesn't really solve any of the problems but can add more like having to hide the injuries from those she doesn't want to know, and that there is always a risk of infection. If you want, you can give her this alternatives list. These are better ways to cope.

Also encourage her to seek help. You can let her know you're not going to force her into it, but explain how someone like a guidance counselor, teacher, school nurse, doctor, club adviser or coach, religious leader, or family member, can really help her cope with the things going on or solve some of the problems.

If you ever think that she is in any serious danger that threatens her safety, do report it so she can get help.

You're a great friend for caring so much!
