Validation like HazelGirl said.

I think the thing with validation is that it allows you to feel worthy. You are important to your parents (and therapist). What you say matters.

Because we are so vulnerable and easily influenced while developing, parents who don't validate you deny your experience, which in effect, denies who you are. That leads to a un/under developed sense of self. Sometimes a false sense of self. Invalidation is not usually done consciously, but it could be done by someone who is self-centered, or anxious...etc.
