Dude.
You're ok.
These things happen, and they enlighten us. You already acknowledged that the reaction was over the top; is there a point in giving yourself grief over the reaction?
Anger is human.
The reaction is done. It's not you. It was an outburst of frustration.
And now?
That reaction is in the past. Gone like a fart in the wind.
You are only human doing human things.
