How to stop breaking stuff when I get angry?

A lot of things have gone wrong in the last few years, and I break things then I'm angry…
I kicked my TV, It didn't break but there's 2 dead pixels in the top left
I HIT my laptop and the screen cracked,
I Threw my iPhone at the wall and the back is shattered, but I have insurance so it is ok
I even smashed my brothers iPod touch by hitting it against the bathroom tiles, but he never found out because he hasn't used it in 3 years…

How can I stop breaking stuff when I'm angry?
I'm 18 and I'm moving out soon, should I see a psychiatrist?

Under neath is what happened to my iPhone 4S, I can still use it and I have a case to cover the back.

You may need to seek counseling for your anger management. Another thing you can do to keep from breaking valuable things is to find a doll and keep it handy. When you get angry, throw it on the floor and stomp on it until the anger passes. Later, when you realize how foolish you must have looked, it might be a good incentive to learn self control for your anger tandrums.
