What were you expecting? How much research did you do about the role before you went to school? I've been a psych CNS for many years, currently working on an inpatient psychiatric consultation & liaison service in a large academic medical center, and, yes, we spend at least as much time writing as we do talking to people. That's the nature of healthcare these days, and it's not likely to change.
In my experience, there's a lot less writing in outpatient (some providers write only brief, vague eval and progress notes), but it's been a long time since I worked in outpatient so I don't know how much that may have changed.
Since you mention you're new, some of the issue may just be getting more familiar with and adept at documentation and your specific organization's medical record system. You will probably get more efficient as you get more experience. Also, in my experience, new people tend to over-document out of their own insecurity (I'm not saying that as a criticism, just a natural part of the process of gaining experience and confidence over time).
