so sorry for your loss, however...... please do research first and educate yourself on how to keep and feed them properly, make sure you know exactly what has happened with that frog and that the other one is ok. and get a new one only when you confident you are able to provide and care for them, including vet care.
mealworms is not a food for a frog due to very high chitin content, they posses very high impaction risk if given in big quantities, that untreated will cause frog death, that I'm sure happened here.

don't feed your remaining baby mealworms and switch them to nightcrawlers. keep in proper conditions and watch very closely how it is doing. one bath with honey if impacted may not do much, depending on a level of impaction, that is why experienced in amphibians vet should be a call away and you ready to get him in if needed asap.
i hope your baby is gonna be all right.
