Hello mybabygirl,
We are glad you are here looking for help for your daughter. I'm sorry she is in such intense pain right now. Did something specific happen that set this episode in motion? Is she on any meds to address the depression?
One basic need that your daughter has, and we all have, is to feel like someone hears and understands us. This can be accomplished with heartfelt validation. Here is some info to help you understand how to practice this skill with your daughter and others in your life:
