They won't take away your daughter for being depressed, they'll get you the help you need and try to figure out a care plan for you. Maybe you'll need some medication and a friend or family member to pitch in for awhile and maybe some therapy. It's very common to have ppd, way more common than people think. Being a parent is really hard. Don't be afraid to be honest about how you're feeling, the fact that you care about your daughter and you want to get better will show the psychologist that you're a good mom and you are taking care of her.
