Emotionally sensitive people often struggle with trusting their internal experience. They have been told so often, "You're too sensitive," or "You are such a drama queen, " or "You always over-react," that they believe there is something wrong with them.
Others frequently don't understand the intense emotions that the emotionally sensitive experience. In my experience, this leads many emotionally sensitive people to look to others for how they are supposed to feel, think, and act.
They are sometimes fearful they can't manage their intense emotions on their own, so they look to others for help. This can lead to clinging or holding on too tightly to others.
