I'm doing everything I can to subdue my anxieties, and it's slowly working, but this is one of those times where it's an occasional setback.

If say, I did fracture my skull from doing it, it would hurt like hell right? I would get a terrible headache even though it's only a tiny hole due to the pointy edge of the knife. I mean, my nails almost hurt equally much if pressing on the head. But if it hypothetically did penetrate the skull in any way, even by a tiny bit, signs and symptoms would always occur right? No longer scared of the blunt part of the knife impacting the head, now it's more if it could've. stabbed through the skull creating a small hole I wouldn't notice or feel.

EDIT:
It sounds like I stabbed myself in my head with a sharp focused blow, but its nothing like that. More like the force of dropping the knife from a low altitude impacting with the tip of the knife.
