People get sick and sometimes they get better and sometimes they don't. And it doesn't matter if the sickness is cancer or if it's depression. Sometimes the drugs work and sometimes they don't. Sometimes the drugs work for a while and then they stop. Sometimes the alternative stuff works and sometimes it doesn't. And sometimes you wonder if no outside interference makes any difference at all; if an illness is like a storm, if it simply has to run its course and, at the end of it, depending on how robust you are, you will be alive. Or you will be dead.
