It's a very difficult scenario because on the one hand, self harm is an incredibly personal and private act. It reveals a great deal about our emotional resilience and general wellbeing. Sometimes we don't want it revealed to us that even those who are paid to care actually couldn't any less. Sometimes exposing even more vulnerability puts us into a spot where we can't guarantee our own safety or dependency on others for help. Sometimes we don't want to let professionals down even though a lot of the time it's the other way around. The reasons are endless really. But the focus shouldn't be so much on the act but what the act is symptomatic of - if you're finding it harder to cope then that's what they need to know. Leave it to them to ask about what's making you feel this is the case. That then is an adequate time to talk about SH within context. Hope this helps.
