Not a knock on nurse practitioners but I personally wouldn't be getting a mental health diagnosis from anybody except a clinical psychologist or a psychiatrist. Preferably one that has a special interest in whatever you are seeking help for as well as age group. I know this can be prohibitive but diagnostic criteria for this stuff is so much more subjective than any other field in health I would want somebody at the highest level of expertise.
I come from a healthcare background and while nurse practitioners are great I honestly feel their role is best suited to maintenence and tweaking of treatment with most of the diagnosis handled by a much more specialised practitioner.
Also in terms of viewing a diagnosis as having been given "another chronic condition" : just remember that it's something you have already been living with, it just now has a description and you can recieve targeted help.
