It's nothing special. I'm an academic and usually I balance my desire to work / deadlines and family obligations. The last month I screwed up my management and got frustrated at both. I was holding that emotion even after crunch-time had passed.

Sometimes a lighthearted piece is all you need to remember to release. What's the saying? "The sea of bitterness is vast. Turn back, and you may yet see shore." I still love what I do, even if it got tougher than expected for a moment.
