The correct answer accomplishes that. Blow one's top = lose one's temper.

Count to ten before you say anything and don't blow your top.

Using "anything" seems to me guite strange. I thought there is more proper to use "something" in affirmative sentence. Can anybody explain that?

.
'Anything' sound fine to me-- here, the advice is to say nothing whatsoever.

Hi Innominata,

'Anything' suggests here any single word - one single word. It's like the wording at the customs barrier at the entrance to another country where you possibly have an extra tax to pay if you have bought anything. You are asked to declare (reveal/show) anything you have bought.
