What i do i bite my nails and i eat them can you die from it plus i've been doing my whole life.

You cannot: "die" from eating your nails BUT it's a sign of anxiety which SHOULD be dealt with! Hope this is helpful! Dr Z

Nail biting: Biting and swallowing bits of nail would not cause anyone to die. Nail biting can be a form of obsessive compulsive disorder (OCD) that is treatable with cognitive behavioral therapy, behavioral therapy and sometimes psychotropic medications.
