Okay so I am student to be a nail tech and I have done pretty well at most things I've tried thus far except of course for the electric file and I was having problems with my doll handsome some of my fellow student suggested that I practice on my own hand which I thought was a great idea. What I didn't think about was that I had injured my hand previously that week and couldn't really feel my fingertips like then and ended up filing away my entire nail plate now it's splitting down the center and I don't know what to do any ideas....
