It’s tough to see someone simply give up on themselves and lose all faith in their ability to thrive. When it’s a friend or family member, you do what you can to help, with the understanding that they will attempt to help themselves as well. In this case, my daughter won’t do anything to help herself and is willing to let my wife and I do everything for her. Part of me wants to let her sink or swim, but I can’t do that. I’m not willing to let her be without health care or let her be homeless or destitute, or even committed to a long-term mental hospital. She wants others to take care of everything for her, including her health, and she can’t or won’t understand that she needs to be a partner in this. Until she agrees to take some responsibility for her own health, I don’t know what else to do. I wish I had a better answer.
