Not being able to help someone really in need

Currently in the midst of a dilemma, my friend of years has zero money and hasn’t eaten properly in two days can’t get to the shops because he’s currently ill, can’t move around and has no mode of transportation, no family or friends to help get him to the shops and then the added problem of in overdraft that the bank has frozen his account so I can’t send even a little bit to get him by for next week because the overdraft will eat it up and he just can’t get into the shops anyway. I’m too far to hand money over or buy bits for him. I’ve had a massive cry knowing he’s hungry and won’t be able to get any help, any suggestions/advice?
