Yes, I used to be a self harmer...
But I try not to anymore.
But every once in a while, when I'm all alone, I find myseld expressing my anger and sorrows through my arms instead of my poetry, that one of the main reasons why I write poetry.
But this is really good, and you hit all the points of the habit as well.
It is very good, you have a knick for poetry, never stop writing!!
