Had a rough parenting moment and need perspective

So yesterday I totally lost it with my 10yo over homework. Like raised my voice, frustrated, the whole thing. He shut down completely and we didn't talk for like 2 hours. I apologized later but I'm still feeling gross about it. He didn't deserve that reaction - he was genuinely trying and just frustrated himself. I hate when I let my own stress spill over onto him. How do you guys bounce back from those? Like I said sorry but I want to actually do better tomorrow, not just move on.
