I'm a bit nonchalant about my scars so on the one occasion a nurse spotted them and commented, it was very much water off of a ducks back for me... I don't cut because of how others see me, it doesn't define who I am; I cut because it's a release (well, I'm trying not to these days obviously):

Anyway, had an escorted trip to another hospital for a medical procedure (was inpatient for mh at the time) and the nurse spotted the mass of recent cuts and quite sharply said 'you're a self harmer then' to which I nodded and said 'yes'... short and sweet. My non reaction in terms of embarrassment or whatever cut that conversation short
