I know so.
You may have a slip-up at some point, but it's never a failure. Hey, even if something were to happen tonight, at least you know you can make it for 4 days. And next time you'd try for at least 5. I don't think anyone makes a decision to quit and then never cuts again. Everyone stumbles a little on the way. I remember I had gotten to about 6 months without cutting, and then I had a spectacularly bad day and I now have the scar to prove it. But I didn't let it stop me, and I haven't cut again since. You can do this. Just stay strong. We're all here for you.
