My toe nail has fallen off, ive got dry skin and my bottom lip is always cracked and dry?

First of all your weight isn't that bad and you should start eating alot more especially breakfast because that is the most important meal of the day. If your toe nail just fell off it could be a fungal infection and many other things if your concerned you should go see a doctor but in advance for (maybe) next time you can buy a nail hardener and protecter from a local drug store in the same isle as the nail polishes. You should moisturize regularly especially after a bath or shower because once you've dried your body your skin becomes dryed out and begins to crack so remember to moisturize often. My bottom lip is often dry and cracked and there are many cause for this such as weather and dryness use a lip balm or vaseline regularly like before you go to bed that way when you wake up in the morning your lips will be soft.

you're able to exfoliate your lips regularly to slough of dry epidermis on your lips. Use your toothbrush and gently brush your lips, this is going to help, and use a lipbalm or lip moisturizer each and all the time. and ensure you're hydrated too
