It's rare for a person to go from 0 to 100 over a single incident.

Some continuing situation in your life is keeping you at 99 at all times and then a minor irritation with your family pushes you over the edge every time.

Find a good therapist and start unpacking whatever it is that's keeping your anger on the edge of explosion. Do it soon because one by one, your close people will start deciding you're not worth the trouble and will begin distancing themselves from you.
