I just read an article which talked about Bipolar disorder, and some guy had commented on it saying: 'what your describing is not really bipolar, it's manic depression.... two completely different mental illnesses. bipolar's rather tricky to describe. the most obvious symptoms are narcissism, inappropriate moods/behaviors, recklessness/fearless, and some symptoms that are common but not always present are sexual promiscuity, hallucinating, hearing voices and coming off as a real nut job so to speak. manic depression is more cycles of mania and depression. depending on what type of manic depression you have, you could suffer from more episodes of mania than depression, vice versa, or a straight up 50/50.' Has anyone else ever heard/read this sort of thing before? I found a little funny to be honest, as it seemed quite absurd for someone to think Bipolar and Manic Depression are completely different things.
