Personally, I would err on the side of catching them when they say that they love you or some affectionate thing, then asking more clearly something like "you love me, right?" Then when they'll undoubtedly say yes, then you say something like, "then I feel like I need to say something...."
Just think it out, feel it out, and say it at the right moment. I cannot guarantee that this is a good solution, but it says to your parents that you value their love and that your identity has nothing to do with how you feel about them.
