I think what they may have meant is, don't wait until you are certain you have hit rock bottom and then start to work on the things that will make you feel better, do it now. Not five minutes from now. Now now. Because there is no bottom. Your inner void in infinite. And the longer you fall the longer is the climb upwards.

Or I just read too much into what they said and then projected my own knowledge of my personal misery onto the topic at hand.
