You’ve got to think of it this way, you done it once and you stopped - your best friend doesn’t need to say anything. I mean, sure, some reassurance would be lovely, but she can’t exactly say I want you to stop when you’ve already stopped? Nonetheless, if I was you - I’d still be upset about it. Ask her about it, what she thinks about it. Why are you so upset? No-one deserves to feel pain when it’s not their fault. I’m sure you a lovely, strong and beautiful person. You shouldn’t harm yourself, you don’t deserve that. I promise, you a beautiful. Things may get worse but soon, they’ll pick themselves up and get better xx
