Just because someone has not thanked you for a favor you did for them or acknowledged something generous you gave them does not mean they don't appreciate it. You are a highly sensitive individual, dear Cancer, and you do have a tendency to overanalyze situations of this kind. You don't do things for recognition - you do them because you have a kind, generous, and very warm heart. Yet at the same time, you have a deep need to know you're appreciated. Not everyone expresses gratitude in the same way, but if you pay attention, you will see the signs that you are loved.
