My left hands index finger's nail is so badly bitten, that there are literally dents in the nail itself. It started a little while ago, I used to have a little bite when I felt tempted to, and then there was a layer on top of the nail, it was clear and invisible, though I would nibble at the nail a little bit, until I'd rip the nail off. I'd get pure satisfaction from doing this, and so I found it easier to rip layers off the corners of my index finger's nail. Soon, the nail started to get really short. The white part under my cuticle, or otherwise known as a 'moon' which are quite large on all my nails, started to fade in half, and then there was only half a moon in the nail. The bits of layers were hidden under the cuticle, so I would dig right under and rip it out my teeth. As sore and gory as it sounds, it didn't hurt at all. Soon, the last few layers got really thick, so I stopped ripping them. There is now half a layer showing, and a dent on the top half of my nail, where it is really soft and easy to push on. A good little while ago, there was even pus coming out from the top of my nail. Please help me! I need to get over this habit ASAP before I start to bite at my other nails! I have tried plasters but they just fall off, and I bite through the yuck tasting nail polish. My family situation right now means it's almost impossible to see a doctor or get any thing from a chemist! Please list help for me! I'm starting to think it could be an anxiety symptom, as my lips are bitten at too, and I am always jumpy and can not stand or walk around certain places. I also get frights even though I know their coming, could biting my nails be a sypmton and my very very very extreme jumpiness be apart of it too?
