If you notice someone around you avoids social activities, has frequent wounds and bandages, and wears long sleeves/shorts even in hot weather, they may be self-harming. Other signs might be impulsivity, trouble in interpersonal relationships, and expressions of worthlessness/hopelessness. If you think someone is struggling with self-harm, start a safe conversation with them and ask if they’re okay and if they need support. Be there for them—listen attentively to what they’re saying and don’t invalidate their feelings/actions. You can also lightly encourage them to see a doctor or a mental health professional if possible, but never force it on someone unless they’re ready.
