Hello hsalmon21: The only thing you can really do here is to be available to provide whatever support your friend seeks. Be available to talk. Perhaps try to do some fun things together as the opportunity arises. You've encouraged her to see a therapist. Apparently this is not something she is ready to do, at least at this time. Perhaps she may come around to it at some point in the future. But it's her decision. In the meantime, what is important here is for you to take care of yourself. No good will result if you allow this family's sadness & dysfunction to swamp you as well. I wish you well.
