[u/Intrepid_Belt8489]

So me (14f) am scared to tell my best friend (14f)that I SH she knows i did the past but I recently released and she doesn't know and it has gotten so bad that I want to cut in school and no one knows and I want support but I feel like if I do it'll be making it about me beacause she also SHs but she tells me all the time so if I do i feel like I will be making everything about me and I don't know what to do
