<human>: My boyfriend discretely will tell me he doesn't like that I bite my nails, and I (f) absolutely HATE that I bite my nails. I have been doing it for probably about 9 years now, and I have tried everything I can think of to stop. I have used many different kinds of nail polishes to help them grow and to prevent me from biting them, but my mind doesn't care.. and I end up biting right through the gross polish. I also tried getting my nails done (with acrylic nails), but if one chips.. I end up biting them all off. Is there anything I can do? I just want this to stop! :(

Can you condense the text into a few key points?
<bot>: I can't stop biting my nails. Need method to stop it. I've tried acrylic nails, and different nail polishes to prevent biting.
