Will you just staaaaaaahp already?!?! Stop calling yourself worthless. Tell yourself, "I am worth everything, and I love myself." And see the results. When I first came into foster care, I told my foster mother, "I get sick every holiday" and she told me to stop saying that, to say I feel great everyday and I am never sick. I have been sick once this year, and only because I had food poisoning. What you say is what your universe and mind believe so fix your mind set.
