If you’re very agitated when you start meditating, how long does it take you to calm down?

I don't know how long it takes me to calm down. Whenever I am upset & I'm trying to concentrate on the task at hand I try to change my mindset such as what's making me upset to something that makes me happy, calm & peaceful. I continue to do this until I forget what I was upset about & I keep my mind on those things so that I won't go back to what I was upset about.
