Ever poured your heart out in dua, only to feel like the answer was no?

Assalamualaikum, everyone. I was thinking about those times when we really, really want something, make constant dua for it, and it still doesn’t happen. It’s a tough spot to be in. Could you share your own experiences? 1. How did you handle that moment of disappointment? 2. Did it shake your iman or change how you relate to Allah? 3. Now, with some time passed, do you see any wisdom in why it didn’t work out? 4. Did something better end up coming along, or did your way of looking at things just shift over time? It's not easy to accept when things don’t go as we hope, especially when we’ve been so sincere in our prayers. I’d really value hearing your personal stories and reflections.
