My father borrowed all my savings and hasn’t paid me back-any du’a for getting a loan returned?

Assalamu alaikum. I’m a stay-at-home mom, and my husband’s income barely covers our basic needs. Before marriage, I saved some money for emergencies. Two years ago, my father needed cash to pay off a debt he was being pressured about, so I gave him everything I had, trusting his promise to repay me in a couple of months. Now, we’re really struggling, and my kids go without because we can’t afford extras. Meanwhile, my father and his wife earn well, and I see him spending on unnecessary things without any urgency to return my money. I feel guilty complaining about my own father, and I want to be generous, but it hurts to watch him waste while we suffer. I can’t bring it up with him because our communication is strained and never leads to a solution. I gave him everything thinking he was in dire need, but now I’m left with nothing and feel bitter every time I can’t provide for my children. What would you do? And are there specific du’as or hadiths I can recite to help recover my money?
