The power of istighfar and salawat in tough times

As-salamu alaykum, everyone! I need some motivation and real stories to keep me going with dhikr. I try my best to do at least 1,000 istighfar and 500 salawat daily. Usually, even my most impossible duas come true. But lately, my whole life turned upside down, and I'm really sad and struggling. It feels like Allah isn't listening, even though I know He is-He's always been with me, even at my lowest. This silence and the hardships (marriage issues, hating my job, and feeling negative about myself again) are really getting to me. I feel almost hopeless. I keep trying to tell myself that Allah is there and to remember the things I'm grateful for, because my life is still better than it was 2.5 years ago, alhamdulillah.
