Narcissist lyrics

[Lyrics from Snippet]
I swear to god, I don’t deserve this
But you do
Little did I know you would make me sick
Little did I know would it come to this
Yeah, I guess
You’re toxic, psychotic, bad for my health
Little did I know you would get your kicks
Treating me like the way you did
Yeah, I guess
You’re toxic, neurotic [?]
Little did I know you’re a narcissist
Na-ah-high
Little did I know you’re a narcissist
Na-ah-ah-high
