Struggling to Pray and Keep Iman Strong - Need Advice on Getting Back on Track

Salam, everyone. I'm really having a hard time with my faith lately; it feels like everything's falling apart. I used to pray all five salah without fail, read Quran often, and even wake up for tahajjud. I kept asking Allah for help through dua, thinking things would improve as I tried to better myself. But honestly, even with all that extra worship, I haven't seen much change in my situation, and it's started to wear me down. It's made me wonder why good things aren't happening, and I've slipped into doing things I shouldn't. I want to return to how I was, practicing properly and staying away from sin, but I'm really struggling and just looking for some support or advice from the community. Jazakallah khair.
