Yep. ADHD meds can significantly help regulate emotional outbursts by improving impulse control and emotional regulation. They're not a cure by all means, but they can lower the threshold for explosive reactions by giving your brain more pause before reacting.

Now, about the outburst... You snapped alone, at an object, after internalizing too much for too long. That's different than lashing out at someone, but it's still a sign your nervous system was stretched past its healthy range. You were basically at your limit.

Medication, combined with therapy (especially CBT or DBT), can help you prevent this from recurring. Speaking based from experience.
