The best you can do in such case is to make duaa for them and all of the Muslims.

I am very disturbed these days. Whenever I see people who are financially struggling and poor kids on the internet or on Streers my heart becomes very sad and I don’t have so much wealth and reach to help them. I sometimes am not even able to sleep properly because their faces are in front of me. What is our role as a Muslim and what is that I should do? Please advise me
