Hello ... Besides psychotherapy ...( learn ways to control impulses ) you need to see your medical Doctor to rule out epilepsy ( very unlikely )
But if all is normal medically you need to see a Psychiatrist and get evaluated to rule out Attention deficit disorder , impulse control disorder and bipolar disorder . Impulse control can be a major issue for people who have abnormalities in their frontal lobe... They can manifest as any of these disorder and can be very well controlled with medications .. And significantly improve your performance in school , job , relationships and over all quality of life .
Do get help ... !
