Where did it all go wrong..
It doesn’t have to be wrong. Cutting isn’t the problem here: the problem is the condition that drives you to hurt yourself. You did not choose this condition; it is not your fail that you live with it.
The time will come when you no longer feel driven to self harm. Your wounds will heal and the scars will fade. Until then you need to know that you are stronger than you know. Please stay strong valiant warrior.
