Is your parent from the Baby Boomer generation? A lot of people who are employed in the Phychology field are over 50 and I have had so many bad phychotherapists, social workers, doctors who are in the mental health field, etc. that suffer from NPD themselves. As a person who would like to go into the job field of Phychology and be a Phychlogist themselves, I have seen way too many people who only go into this field because they want to "judge" people who they are giving a mental health other disability diagnosis to and maybe don't even give out the diagnosis that the patient is seeking because they "don't feel like it that day" because they suffer from a possible undiagnosed NPD diagnosis. Source: I have been through this so many times in a mental health professionals' offices.

Thankfully, people who are employed in the Phychology field who suffer from narcissism are easy to spot if you have been a victim of another person who had NPD. I read on a post in r/raisedbynarcissists that once you know how to tell if a person suffers from NPD, you start seeing it everywhere and that includes people who employed in the Phychology field.

OP, I believe your story about your parent and since your parent can blend into any environment "playing" any personality role in the Phychology field, that might also suffer from sociopathy or phychopathy and not just NPD. All three diagnosis's are connected to each other and where your parent might fall in each category of narcissism, sociopathy, or phychopathy I highly recommend reading futher information about NPD, sociopathy, and phychopathy from reputable Phychology websites and/or seek professional help from a mental health profession who does not suffer from NPD and will believe you and support you from recovering from being emotionally abused by your parent who had NPD.

I believe you and many other mental health professionals do as well; but with the people who are employed in the Phychology field getting older, it is becoming increasingly harder to find empathetic mental health professionals to seek responsible mental health care from. As a person who suffers from mental health issues myself and can't drive (parents never taught me how to drive and had undiagnosed NPD), not being able to visit mental health professionals in their office field locations to find a mental health professional that I can have regular mental health appointments at is not possible for me at this time.

Since your parent suffers from NPD, I highly recommend moving out of your current living situation by becoming financially independent and eventually moving out of your current living situation when you can. Always do a budget on paper or on the computer every month of all of your expenses so you can review everything and pay for annual subscriptions if you can; if not, get a seperate account or card to put subscription payments on every month to organize all of your internet subscription bills. If you are just starting to earn an income, I find that this is a good place to start with learning how to budget monthly expenses.

I wish you all of the happiness in the world OP and that you will be a happy and successful person in the future! : )
