I know it's hard, but you don't
need to cut. You may be experiencing a strong urge, and it may feel irresistible, but you can choose not to.
I'm not trying to imply that it's that easy and simple, but you are not powerless over this.
This is what I tell myself when I get a strong urge to drink or cut and I feel like I
need to do it:
Urges pass. Take a deep breath. Then another. You can ride out the urge without cutting, and every time you do it without cutting it will become easier the next time. Urges are extremely uncomfortable, but they are not truly unbearable. An urge itself cannot hurt you, it is temporary, and it will pass.
Whether or not you decide to cut, I'm sorry you're feeling so awful right now
