After you shower/bath and are all clean and ready to go out for your day...dip your fingers into something horrible,clean behind the toilet and dont wash your hands after....that would work for me...just dont forget and start nibbling away lol.
Put on lotion instead. Put on pretty nail polish that you like enough that when you look at your nails you don't wanna pick at it & mess it up. Wear rings as a distraction.
put bandaids on all of your fingers?.. my friend did that for a few weeks and it helped.
I know it sounds weird but .. it works
Try to keep yourself occupied, so you dont even think about that!
hey i have the same problem iv done it since i was a little kid
