Is there anything more I can do, brothers and sisters?

Salam everyone, I need to share what's been weighing on me. I often see news about the occupation and suffering of our ummah and it really upsets me. There's this heavy shame and guilt I can't fully explain. Sitting comfortably in my home in a wealthy country makes me feel powerless. I've given donations and made dua, but I keep feeling there must be more I can do through action. As a Korean revert, I'm caught between my values and my family's views. My family aren't directly affected and whenever I bring it up they're like, “why do you care? it doesn't affect you.” I'm not blaming them - I can understand their perspective - but as a Muslim and as a human being, I feel in my heart that we can't ignore such injustice. Palestine is occupied now, and my motherland Korea was occupied in the past. I wasn't personally affected by that either, but I can see how deep the wounds and history of such wrongs run. I recently spoke with a professor who did emergency relief in Gaza and they suggested that if I want to work in humanitarian fields, I should start by looking at the UN. I'm in the process of applying for UN positions. I'm still a university student, so we'll see how it goes. I'm not sure if I'm asking for concrete advice; this is mostly what's been on my mind. But I'd appreciate any thoughts or suggestions you might have - especially from fellow Muslims who have navigated similar feelings or careers. JazakAllah khair.
