How can I cover my arm? I was getting stressed this morning and my boyfriend was making me upset and I got so angry and upset that I self-harmed and now it's really red and it's at the bottom of my hand right next to my hand so it's visible and easy to see. I've got make up power but I don't know if there's anything else I can do to stop it and I'm 13 and have school on Monday and pe 😔
