I self harm regularly on my left wrist. I recently stopped cause I got my scars tattooed over, whilst it was liberating to be able to go out in a t shirt again, I miss the feeling it gave me, but I won't destroy a piece of art.
We as humans are supposed to feel pain, if not we create it in our minds, and the mind creates more pain that physical ever could.
I cut myself to feel, I have no feelings otherwise, just my senses and my sadness. I convinced myself if I tattoo myself I will stop cutting. I have but its on my mind to be able to feel constantly. I can't do anywhere else for reasons I don't want to specify.
It's like for those couple of moments of deep pain, I am alive and I am real, I am human, not the nothingness I see myself as.
