when you are feeling nervous, keep yourself in check. once you
figure out that you are biting yourself, tell yourself to stop. see
if sucking on candy works....
the main problem with these issues is that once people drop one
thing, they tend to pick up another habit (such as biting
nails...)
try to constantly remind yourself not to bite. think of something
or do something else to distract yourself. figure out what makes
you nervous and why they make you feel nervous. take deep breaths,
close your eyes and slowly count to 10 (or 20 or 30 or 50 or
hopefully until maybe you feel a little calmer).
