Darlene, Your question is a valid one. It can be challenging to care for sick and/or injured people. A major part of Nursing is educating, motivating and helping the patient with resources to get well. For example if a patient has been diagnosed with a chronic illness such as diabetes and they must now change how they eat, give themselves injections and monitor their blood sugar it can be very disruptive to their lifestyle and they may not have good family support. Nurses know that the patient may become angry or disheartened with the changes and new responsibilities they have to care for themselves and a good nurse will help the patient through that transition by educating and giving them ongoing resources to help them make the transition.
The best thing for me about being a nurse is that every work day is different and I love the people I work with. I enjoy educating and being a resource for patients. I like that I can work any where I want to live or relocate.
A good thing about nursing is there is a wide variety of types of nursing and you will learn very quickly what you like best. When you like the a type/unit/department of nursing, it is easier to handle difficult patients. Also good work - life balance is important to recharge and have interests, activities and engaging life outside of work.
