How do you cheer or make somebody, who has been faking their emotions and bottling up their feelings, has been abused and cutting themselves happy again?
Hmm... well, I deal with the same thing, so never get angry at them, keep telling them they can always talk to you, be patient, never raise your voice at them or else they’ll be scared of you, if they’re comfortable with it, you can try hugging them and give them physical comfort, NEVER yell at them for cutting again, and idk what else, really, sorry.
