As with any caring profession, an interest in people is essential for any budding Mental Health Nurse. While your study will almost certainly incorporate a great deal of research and you will be expected to attain a high level of knowledge about various mental health conditions, ultimately you will be being trained to care for those who suffer from them. If you enjoy helping people and making a real difference in their lives, and have a non-judgemental attitude to those who are 'different', a career in Mental Health Nursing could be ideal for you. As mentioned above, you will also need the intellectual curiosity, and capacity, to understand the complex mix of Psychology and Biology that goes into creating a mental health condition, so a background in these subjects will be a great help to those starting out in the field.
