How Do I Enjoy Being Pregnant?

I want the baby. I do. I want to enjoy this time of having life grow inside of me. I just don't enjoy how I feel being pregnant. I'm not happy. I'm depressed. I feel alone. It takes all of my energy to not ball up and cry everyday. Everyone tells me that I can count on them, but I feel like a burden to my own family telling them that I'm depressed and anxious all the time. I love my baby, but I hate myself for not being thrilled to have him.
