In my clinical work with troubled teenagers, it is often the case that there is a real communication breakdown between these adolescents and their parents. These teens often feel that their parents do not understand or respect them, do not listen to what they have to say, and cannot relate to their experiences. They may report feeling isolated and closed off from their families, rejected, hurt, angry, anxious, sad, and lonely. In general, these adolescents have built up a “protective wall” between them and their parents (and sometimes the rest of the adult world) behind which they retreat.

Why is it that we are our own worst critics? Why do we say such mean things to ourselves and call ourselves names (e.g., “fat”, “ugly”, “stupid”, “not good enough”, “failure”, etc) when we would never dare to say such awful things to our closest friends or acquaintances?

Indeed, it seems a lot easier to give compliments to others than to accept and to believe the compliments we hear.
