does biting my nails have something to do with my anxiety disorder or my OCD?

no matter how hard i try, i cannot stop biting them. i bite the skin around them til they bleed and i have to put bandaids on them. i have tried every nail polish that is supposed to make me stop biting them, and nothing works. i read that it could be a symptom of anxiety or obsessive compulsive disorder, and i have both of them.
