They've tried, but the husband is her legal guardian. And speculation goes that he doesn't want her to get better because then she might tell the world how she ended up in this condition in the first place. It's just an awful legal mess and tragic for Terri, IMO.

I don't believe that Terri is going to get better. I have had to walk in any of these peoples shoes, but as an outsider I do not see why the husband just doesn't divorce her, and let her parents take her home and treat her. If this were my child, I hope that I would just let her go, but as she is not I would not know how I would react and neither does anyone else that hasn't been there.
