Thank God there are those like me. I can't stop biting my nail skin and lips, gums, and cheeks. Going to the dentist is so embarrassing. When I know I have an appt. it gets even WORSE. A doctor told me once it could be a tic. My son has Tourettes. I try to count to 10 when I get the urge to bite and MAN is it hard, the urge. Might need to go on meds here. On Prozac already but now I'm also hypomanic ugh. I'm so tired lol.
