Go see a nail expert who will stick false acrylic nails on your stubs and make them look nice but natural. Then go back every two weeks to get the infills done. Then slowly the false ones get taken off and your own have grown underneath and you will be proud. Will take about 3 months. At this point they will be weak but keep going so that they can keep them strong and well manicured for you. While the false nails are on you will need some diversionary tactics - after all you have been biting your nails as a habit for years probably. Try taking up something like knitting. No, seriously. (Someone is starting a class on this site!) I know the above will be expensive, but this is exactly what I did, and apart from a few blips it worked for me beautifully. Note: not all manicure specialists (including the Beauty Place on Forest Hill Road) do false nails. Don't go somewhere cheap. It's a horrid habit and I was terribly upset to be owned by this habit for so many years. So I hope you find something to help you. I hate seeing people with bitten nails and know how important it is to break the habit.
