Assalamu alaikum - Struggling with blocked rizq and family betrayal

Assalamu alaikum. I need to share something very personal because my heart is heavy and worn out. I’m not questioning Allah from arrogance - I’m asking because I’m confused and I want advice from a Muslim perspective. My father served in a respected government role his whole life. He never took bribes or did anything haram even when it would have been easy. He chose halal over dunya every time. Whenever someone came to his office needing help, he helped them without asking for anything in return. He trusted that Allah would provide. Now many of those same people no longer speak to us. Our family has faced serious hardships. Two of my brothers have significant mental disabilities, and one has schizophrenia. Caring for them has been heartbreaking and exhausting - emotionally and financially. It feels like a continuous test. After my father retired he tried to start a business so we could have stability. On paper everything seemed right - big deals, millions involved. Things moved forward, we prayed, made du‘a, gave sadaqah and put our trust in Allah. Yet over and over, at the last minute the deal falls apart. Just when relief seems close, it vanishes. What stings more is what happened inside the family. Years ago my father used to send half his salary to his sister and to his mother in the village. He helped build the house there with his own money. He supported relatives for years, got jobs for their children, did countless favors without keeping records or asking for payback. Despite all of that, some aunts later filed a false case against us over land and claimed rights without ever speaking to us or trying to settle things through family or Islamic ways. After everything my father did, they chose courts and accusations. That betrayal hurt worse than the financial loss. All this pressure has changed my father. He’s become harsh and uses profanity now. I can see how disappointment has hardened him. Even so, he still refuses to earn haram; he won’t compromise in money matters because he fears Allah. I wrestle with questions I’m scared to say aloud. Why does rizq feel blocked no matter how sincerely we try? Why do those who earn through haram sometimes seem comfortable while those who stick to halal face loss after loss? Why do people we helped turn away or hurt us? Why do doors close right before they open? I know Allah is Al-’Adl and Al‑Hakim. I know this dunya is a place of tests and not the final reward, and that patience is valuable. But knowing that doesn’t remove the pain of watching my family suffer despite living with integrity. My iman isn’t gone, but it feels wounded and tired. If anyone can share insight from the Quran or Sunnah, or personal experience with delayed or blocked rizq, or wisdom about being tested through family betrayal and financial hardship, I would really appreciate it. I’m not after platitudes - I want truth that helps me hold onto Allah without my heart breaking further. JazakAllahu khairan to anyone who reads and replies.
