Which one is correct? The paranoia of/about secret societies and one world order.

Oh the paranoia of secret societies and one world order..

'Of' or 'About'

Paranoia of? or Paranoia about? Which one is grammatically correct?

And, when you write a formal letter to someone whose name you don't know, what's the best way to address the person?

Hi there, or Dear Sir/Madam?

Thanks

Dear Sir / Madam, is the correct way to address a formal letter.

Paranoia of, is the societys own paranoia.

Paranoia about, is the opinion of others regarding the society.

Finding mistakes:
"I think I won't come to the party"
I think it right. Can you explain it for me?
thank you

Good morning Tiendung. Your sentence is understandable, but it's not a very good one.

Better to say, " I don't think I will be ( going / coming ) to the party."

Kitosdad.
