My Heart Wavers When I Make Dua-How Can I Strengthen My Faith?

Assalamu Alaikum, everyone. For a while now, I’ve been pouring my heart into a specific dua. What I’m asking for isn’t impossible, but it feels really difficult. There’s a wonderful man I wish to marry, but my parents object purely because of cultural differences-he’s a good Muslim-and I’ve been begging Allah to make him my naseeb. But here’s the thing: when I’m making dua, my yaqeen feels so shaky. I’ve added more dhikr, I recite duas from the Quran, I do everything I can, yet I struggle to truly believe that Allah is listening. And it’s not just this dua-I often feel like my supplications are ignored, and I know that lack of certainty might be why they’re not answered. I don’t doubt Allah, but my anxiety and overthinking about the future eat away at my sincerity. I have anxiety, and it really messes with my daily life. I always feel like if I can’t control or plan everything, my life will fall apart and I’ll never be happy. I try so hard to have yaqeen, I listen to sheikhs and uplifting Islamic talks, I keep making dua, I do my dhikr, but I’m scared it’s all pointless without firm faith. Please, help me fix this-or just share some hopeful stories or anything that could lift me up right now. Jazakum Allahu khairan.
