Regressing

I'm frustrated with myself. After a 33-year-old habit of biting my fingernails terribly, I kicked the habit nearly two years ago. Somehow I just stopped. For over a year and a half, I had beautiful nails, and I still do have regular manicures, but recently, like the last two months, I've been biting them, again. They don't look terrible, my cuticles are still intact and I didn't bite too much off, but still. It's a little depressing. I want my pretty nails back! :( :(
