I played mario bros with my brother today and got really pissed off.
Why are you telling me that?
I am impulsive person, I become uncontrollably furious at times, I can get violent too
That must be difficult to deal with. Being angry and impulsive can result in jail time and lawsuits. You need to get help.
It's fine. I can't help it, I'm a victim of my own body.
I'm not blaming you for feeling that way, but there's resources out there that can help you to work on these issues!  I recommend talking to a therapist to work through these anger problems before they get you in serious trouble.
