Welcome. Its usually overwhelming to face all of our issues with our kids at once. Perhaps we could help if you could tell us your most urgent or important problem.
Narcissism is a component or common trait for many. Eg an autistic may not have the social skills to realize that they appear to be narcissistic. A person with anxiety disorder may be so absorbed in their fears that they appear to be narcissistic. That's not to say that they are not narcissists. They may be or they may just appear to be.
