Remember when people go out of their way to point out a flaw in you and diagnosis of you, it is usually a projection of themselves.
My comment back would be, if you muted me why did you respond. Maybe you should research what narcissistic personality disorder is and understand about projection, because you could have just scrolled on by.
I feel sorry for you as a person, and I hope you get the therapy that you obviously need. Be well and get healthy.
