i have got very long nails and dont cut them what should i do? what hand cream cn i use

I would use a crystal nail file that is gentle to your nails and won't cause splitting. good hand creams for dry hands are OPI's Avoplex Hand Lotion for during the day and then a thicker one for night like L'Occitane Shea Butter Hand Cream which will help replenish the dryness also try some moisturising gloves at night to lock the Hand Cream in at night.

To make sure your long nails remain that use cuticle oil daily. Rub it into the skin surrounding cuticle and leave overnight. The oil will nourish the root of the nail, thus, producing more flexible nails which will be resistant to breaking (when you apply pressure it will rather bend) and spiltting.
For dry skin on you hands I would advice regular exfoliation (at least once a week) and paraffin treatment. Also make sure you moisturise your hands every time after you have contact with water.
If the nails feel to sharp use a soft sponge buffer at the edge. This is a good example: http://www.beautyagents.co.uk/epages/es137343.sf/en_GB/?ObjectPath=/Shops/es137343/Products/F1300
