I Spoke Before Thinking Twice

As a stay-at-home parent, I pride myself on being patient and understanding. But today was different. My toddler was having one of those days when nothing could keep them occupied or calm for more than five minutes. In frustration, I blurted out that their constant noise was driving me crazy without any filter. I immediately felt terrible; they looked so hurt and confused. Did I go too far? Is it normal to have such moments but not act on them? What should I do now to repair this?
