Nah, there's a difference.
I used to worry about being schizophrenic, until I did research on it. We're just weird; we're not crazy. The rest of the world thinks we're crazy but only an insane person thinks he or she is normal, or sane.
There's a fine line between genius and madness...but if you can no longer take care of yourself and distinguish between reality and non-reality (and you hurt others or yourself in the process) then it's time to get help.
Sometimes you can tell when folks are dangerously close to the edge, though. It's not a gentle madness; it's something frightening. And it's not in that "they're not intuitive enough to understand" way. It's that paranoid, "you're an alien but the aluminum hat's not working to shut out your vibes so I have to kill you" way.
When you're cloistered from society and you can't function alone any more, then it's time to seek help (and that could be anything from hoarding to agoraphobia to full schizophrenia). Problem is, by the time you get that far, you might not realize you need the help. :\
