You should really listen to the song "echolalia" by dead can dance. You might find yourself in the echoing madness. On a side note, I used to say only animals are mad, and therefore it is only them who can be victims of madness - because humans are crazy. But now that I live in rapacity (swallow that second a and replace it with an E, if you feel me), I can't help but think the distinction between MAN and beast was but a foolish folly.
In other news, unless you're under the influence of some drogue dure, you're definitely the one holding yourself back. You can blame your friends all you want, or the gravity of nothingness (which, I know, I know, it's hard to believe, but actually does have a gravitational pull). But ultimately you are the one who chooses your limits.
Just like you decide when you are done with being sick. Also, add more cliché lines like "falling to pieces" please.
