To me- Yeah I do see scratching as a self harm - weather it be not knowing doing it or knowing doing it- but then I am not any sort of pro on this

I just know when I was younger like a kid to preteen i use to scratch myself, pinch myself, and as a teen i use to cut at times---
then with one of my brothers, when he was under a lot of stress (i do this as well) but would scratch away his skin with out really knowing he was doing it...
I do think with some, it is some sort of release to not in an "appropriate way" to deal with emotions..

but this I do think you should talk to your council about as well- and you two can determine on what it may be the main goal with you and your councilor is to come to a solution and better you For YOU....
