Wrong. You are hurting yourself. You know full well deep down that you are. ED's can kill, as can SH/SI'ing. I could have died from my SH'ing behaviors before, and many have died unintentionally from it. Many have also died and/or suffer from consequences(possibly for the rest of their life) from their ED. It is damaging to your body, and you could very well suffer from consequences for the rest of your life, like many out there already do.

I've been a SH'er since I was 7.
I've had an ED since I was around 12/13.
Both are damaging.
Physically, emotionally and mentally.
