Inconsiderate brother

Went to my Pediatrician (5 min. Away by car) because my baby is sick, got my prescription but had forgotten my wallet. After I went back home my baby was running a 102 fever. So decided to let her sleep and go to the pharmacy later. Her fever wasn't going down so I called up my brother if he could come by- he lives 8 min. Away by car). He said he wasn't going back and forth since it's close by, afterall it's not so cold out not to go out again. I'm so upset because for a fact he would do it for his mates. We are family that's what we do, he's always doing favours for others but for family he is lazy and throws tantrums.

Do I have the right to feel hurt?
