Your ownly 15 years old young sir. Meaning your body is full of testosterone. Meaning you will be more agressive around your puberty years. say 11-18, maybe abit less.Just nature.

I have anger issues aswell, generally it gets easy to control, Music is usually the best relief after a days work, or learning or w/e. Just pick music that you know relaxes you and go to sleep or something.

But my anger manifests itself in rage or swearing. Usually it is never without provocation. As it will only happen when i feel pain when its not expected.
Only thing you can do is to just hold it in. And playing games, never worked for myself, unless its just plain ole fun and not competitive.

At the end its up to you buddy, but you really arent alone, most males of your ages will go through the exact same thing, its just there reaction that might change.
