If someone tells you they appreciate you, you know that it is a personal thing for them to say.
It's not something that is just said or done because society told them it needed to be done for one another- but rather a message the person values you for being in their life.
An appropriate way to provide a response to "I appreciate you" would be "Thank you, I appreciate you too." or "I'm glad you feel that way, thank you."
