My little guy is 6 y/o. He's mature, kind, sweet, and very bright. He thinks he isn't good at anything and has no friends. Anytime anyone speaks of something good and doesn't mention his name, he withers. He's great at many things but chooses to see things through the eyes of a pessimist. He has two older sisters (ages 13 and 11), so he may be feeling like the third wheel or in their shadow. ??? Need an objective point of view. Any advice will be appreciated. Thanks.
