OP: as has already been advised, could you provide details of you set-up (temperatures, substrate, decor etc) and pics of the gecko. Do you know how old she is? Or how much she weighs?
ditto ~ would also suggest getting her and a poo sample checked by a rep vet ~ although it can take a leo a week or so to settle I would be concerned at her being thinner and not opening eyes and a check up could point to any underlaying causes.
Food wise I wouldn't be concerned at her eating crix but not mealies ~ it all depends on what she was raised/fed on previously
