Try not to worry too much. My bloods can be extremely picky eaters. They're basically just lazy. You didn't mention what you were trying to feed your snake. If you're feeding mice, try rat pups. My bloods really like rat fuzzys. What works for me is I thaw out a rat pup and lay the head of the rat pup in the opening to the hide that the snake is laying in, then I leave the room for an hour or more. They will usually eat. Just keeping trying slightly different things until you figure out what your snake likes. Good Luck
