I just want to badly to be happy with what I have. It's not all that bad. What am I missing and why am I missing it? What's my ****ing malfunction?

I want to be happy with the amazing husband I have. I want to be happy with this house. I want to be happy with my job. I want to be happy having a daughter... I should consider myself lucky.

Why do I feel like I am lacking? Why does this life make me want more? I want to make it all go away. And I feel like an awful person because of it.
