Teen daughter depressed?

She could be grieving about her Grandma. My Grandma died about 3 years ago, and I went through a stage of depression for a couple of months. I was really close to her since she lived with my family, and was always around. What helped me to get over my depression was exactly what she is doing now. I went to a couple of counseling groups and talked about how I felt. When you talk about it helps you cope a lot easier than if you bottle it all inside.
