If you are angry for hours maybe try going to exercise or meditate(fixing this issue is actually one of the goals of meditation) or something, but that is above my pay grade.

With my kid, he sometimes does not cool down during a tantrum until he goes in his room for timeout for a few minutes, and he is always measurably calmer after timeout. The recommended timeout time is 1 minute per year of age - it's not like they're abandoned for hours.
