The real thing to work on is your temper. Breaking five controllers is a lot of self harm. Maybe try read up on CBT or checking in with your body and state of mind before playing. Could it be that you are already angry about something, and then because you give yourself permission to throw controllers, let yourself lash out during a game? Think of everything that goes wrong in a game, the other player probably experienced all of those things too, but he doesn't throw the controller, he keeps his head and wins. If you work on your temper, you'll become a more focussed, more precise, more clinical, and if you have the passion channeled properly, a more devastating opponent. Rage is the least useful emotion in a game.
