Most of my work has been with adolescents. The issue is that their problems aren’t something that can be easily fixed in a short acute hospital stay. Many of them have been sexually abused. Most have suffered some kind of abuse/neglect or a huge loss. We don’t have a magic pill for that. In many cases, they are going home to family situations that are less than ideal.
BTW, there are some really good psych nurses out there who will be happy to mentor you if they know you are willing to learn!! I was once a new nurse and working in psych. Yea, there were some nurses who weren’t so nice. There was one who completely bullied me. A lot of them seem harsh at first, but they are really nice once you get to know them. In general, nurses like to be helpful. So I you tell them that you need help, most will be willing to help you.
Just be willing to be a sponge and take in what people are telling you. A lot of the psych techs have a great amount of experience and they can really help you out in a tough situation. Of course you’ll make some mistakes along the way—everybody makes mistakes. Just remember safety is always the first priority, and you’ll be fine.
