Urgent Duas and Advice for a Brother in Deep Hardship

Assalamu alaikum wa rahmatullahi wa barakatuh, dear brothers and sisters. I'm reaching out because I'm in a really tough spot and I need your prayers and any advice you can give. My situation is quite complicated, and I won't go into all the details, but I've been struck with a huge distress that's been going on for a long time. I've been praying, making dhikr, doing istighfar, sending salawat, and giving sadaqah whenever I can, but it feels like Allah's help is silent. I know sabr is important, and this could be a test of my iman, maybe because of my own mistakes, but I've always tried to be a good person, ya know? I've never hurt anyone, never even said a bad word to anyone, and now I'm stuck wondering if being good even matters when my duas seem unanswered. These thoughts feel like whispers from Shaitan, trying to break me, but it's also been four years of living alone, far from my loved ones, with no one to help but Allah. He's saved me before in amazing ways, subhanAllah, but this time the struggle is just so heavy and long-lasting. Please, I'm asking for your duas that Allah brings His relief and takes away this anxiety that's like a dark cloud over me. I'd also appreciate any advice on how to keep my heart calm and my mind steady so I don't spiral further. Honestly, I feel like only a miracle or one accepted dua will pull me out of this. JazakAllahu khairan, everyone. May Allah protect you all from such tests. Fi amanillah.
