Dealing with self-esteem issues at 8??

I am not quite sure how to deal with this?? Last night as I was saying Logan's prayers after we ended. I said, "I love you." And he says, "Well I don't love me." That crushed my heart and soul. Well I continue laying next to him to find out what he means by that. I ask, "Do you mean when you look in the mirror, or you don't love that you are awesome at baseball or reading or math?" He says, "I am weird." I point to myself and say, "HELLO!!, so am I!!, we all are!" He also says that he hates wearing glasses, I again point at myself wearing glasses and tell him that at least his are cool and not the ones that cover his whole face like mine did in elementary.

He is still not cheered up by this point!! I don't know what to do??? He won't talk to me straight. I am tearing up by this point. I tell him his is loved by so many people and I name them and I tell him most of all he is love by God and if he ever need someone to talk to God will always listen and then I teach him about praying. Not the nightly prayers we say (we say Now I Lay Me) I say that every night I just talk to God, I tell him that God knows what we are thinking but he likes to hear us talk too. I told him that he can still talk to daddy and I anytime but if there is ever anything he just needs to get out, to pray.

I am just so worried, what should I do???
