I tear my toenails off and sometimes I cut what causes me to do this

[Snakebyte101]

When I get anxious, nervous, or stressed I pull my toenails off or I cut myself. I was wandering what makes me do this ??

anxiety and stress i bite my nails when my anxiety creeps in my sister used to pull out eyebrow hair and eye lashes i think the only way to fix it is to try curve the behavior and busy your self with somwthing else
