How can I stop biting my nails?

If your legal guardian/s know about your habit, you could see if you can create an agreement with them... for example, if you can not chew your nails for 6 months, you can get something really expensive as a reward. then, keep this up to try to motivate yourself, and hopefully by then, you'll have forgotten your habit. If you need help, go see a psychologist. This could be because you are nervous. BE CONFIDENT! tell yourself that you don't need to chew your nails, force yourself to stop. treat yourself. My guess would be that the swelling would go down. think of it this way. if you get a cut, after a while, it heals up. assume the same for your fingers, although i'm not positive.
