They suffer from mental illness also known as evil spirits. Satan sends demons to steal, kill and destroy. It's such a shame that people die because they don't get treatment for mental illness. So many people drug up because they're more comfortable being in an altered state. Reality is real and should be dealt with as such. You can't hide from yourself because every where you go, there you are. So, whatever the problem is, face it, solve it and move with a lightness because you've cleared up the matter. It's okay if other problems arise, because they're bound to. Just solve them; since, they don't disappear without being solved. You'll manage life in a more conscious state.
