There's just a lack of knowledge, I think. Maybe some of the stigma that's been around for decades has stuck with them too, so maybe they think, well, I don't know, is the person just kind of weak and can they snap out of it? So again, lack of knowledge and that stigma thing are the major obstacles. Plus, they're trying to do everything they can for that person, and they may not know what to do. You just come to a point where you run out of options.
At the same time, you can only push this person so far. They have to want the help themselves or they're not going to stick with it.
