What happened? (what would you call this?)?

Sounds like rage, you were really angry, couldn't satisfy your anger, if you understand what that means, so that is what made you frustrated, you may have come to terms with your anger but were still upset about it, hence wanted to destroy something/vent, the last step you describe I guess you could call a sort of apathy, or lack of caring anymore, meaning the current/past situation no longer bothered you. This is all just a hypothesis of course and I can't really be sure, and I'm no professional, so it is probably best to take another persons word for it over mine, especially if they have a reliable source.
