My 8-year-old daughter has been a wonderful child until about a month ago. She’s lying a lot, not doing what we ask her to do, and she talks back. I have asked her what is wrong, and she tells me nothing. Then, when I ask her again, she tells me that she doesn’t feel loved, and I know that is not true. Then she says that we love her baby brother more than her, and that is not true. I don't know what to do because she never acts like this. I’ve taken her phone and other things but she doesn’t seem to care. What do I do?
