My husband is bipolar and has been hospitalized twice and is threatening to have to be hospitalized again soon. Spring time is always bad for him and the most likely time to have to go into the hospital.
However, there, he not only gets a lot of therapy, but also gets to get his medication tweeked in an environment that is safe. In additon, they have craft classes and help the patients find a way to help themselves relax and deal a little bit better with the tough moments.
Your wife should definately do it.
