Hello BlueEyez87: I read your post yesterday but did not reply since I didn't think I really had anything useful to contribute. However, since no one else has yet replied to your post, I thought I would.

I'm an older person now. However, many years ago, when I was growing up, I bit my nails. As a young adult I wanted to break myself of the habit. What I did was to simply keep my nails trimmed very short. I also carried a fingernail clipper with me at all times. Anytime I would notice any roughness to a nail, or loose skin around them, I would use the fingernail clipper to trim it & smooth it over right away. This worked for me.

Of course, as you are clearly aware, the compulsion to bite your nails is a symptom of underlying issues... anxiety, fear, etc... one that over the years has become a deep-seated habit or compulsion. So, while figuring out some way to stop biting your nails is certainly worthwhile, what would be of even more benefit would be if you could resolve the mental health issues that are at the root of this habit. I wish you well...
