I know exactly what you are talking about
and it can be very scary! I have not figured out the magic trick to making this all better but I know what I do is just try to be alone and I use different breathing exercises to calm myself down (almost like a form of meditation)---it has definitely kept me from blowing up like a bomb. If you ever get like that and just want to talk...u can find me online at email@example.com
...contact me anytime.
