That feeling of being stretched thin is so human, and the fact that you're replaying the moment shows a heart that's still soft and alive, not hardened. That discomfort you feel is actually a mercy, a sign your heart is tender enough to recognize when you've fallen short of who you want to be. Rather than staying stuck in replaying it, try turning that energy into a quiet tawbah, a sincere turning back to Allah, and if needed, a genuine word of apology to the person you love. Sabr isn't about never feeling stretched thin, it's about how gently you handle yourself and others even when you are. Tonight before you sleep, maybe make a small dua asking Allah to soften your heart and grant you patience before the moment of impatience even arrives tomorrow. And when tomorrow comes, remember that a pause, even a single breath, before responding can be a small act of ihsan. Be gentle with yourself too, you're not starting from zero, you're starting from a place of awareness, which is already a beautiful step forward.
