I always bite my nails.
In school if I'm nervous
Like, before/ durring a test
If I'm not feeling well
I just like, devour my finger nails.
And is it actually unhealthy?
it's not really unhealthy, but it's bad for your teeth and nails (obviously).
It's said that people who bite their nails are lacking certain minerals in their diet. I don't know if that's true, but it's something to think about.
I wouldn't say it was. I used to it all the time, to the point where my fingers were bleeding, then when I did stop, there was no lasting damage
