I want to tell him how much he sucks! help!

I am so tempted to tell him exactly how much he sucks:

About how he looks 60, and how he needs Viagra
Asking him where all the beautiful women are
Asking him why he pushes trolleys on other people's films while much younger men get to shoot them
Where are his awards, films, exhibitions?
Why did his ex dump him for someone much younger who owned his own house?
Why this guy has absolutely nothing except an old 16mm film camera and a couple of trucks, but is paranoid some gold digger is going to take everything he has?
Telling him that everyone sees right through his pretentious bullshit and they laugh at him behind his back.
That he will never get anywhere and is a complete fucking failure.
And an incurable Narcissist who is incapable of feeling anything genuine. How can he write a film script if he doesn't understand people and their emotions?

I even wrote it all out on a facebook message, but didn't send it.
It is just so unworthy of me.
I have never felt so hateful and spiteful towards anyone in my entire life.
I am turning into a narcissist in daily life just to try and prove that I am NOT unworthy!
