No, it isn't assisted death. A living will is something entirely different.
Assisted death is the end of life by giving some drug to end the life......in this country illegal at present, but in other countries the drug is prescribed by a physician but the patient themselves administer the drug which will kill them.
In a living will the patient will have signed a legal document which outlines that no medical interventions are to be used to extend their life. This does not usually mean the withdrawal of nursing care to keep them comfortable, or pain free. It is recognised by the nursing and medical profession.
