She is Junior, same grade as me. That is all I have to say I do not know how else to explain her, I barely know her.

So... I have these marks on my arms because I Self harm,( I do not cut).

So, I was going to one of my classes, & she asked I was ok. I said yes, I was. She said I she is always there to talk to me.

IDK what to do. I don't her really, & I never had really talked to her. I am struggling with SH, depression, & most of all overwhelming thoughts of suicide.

Should I tell her this to? Do you think she would tell a teacher or someone like that?
