Is there such a thing as hitting “rock bottom”?

We’re always told “once you hit rock bottom…” that we’ll see how bad it is and will finally change our lives, etc. I hear that ALL the time. But is there such a thing as a bottom? Every time I hit a new low, at some point that new low gets shattered and it hits lower, and lower. Has been hell the last decade or so. So is there a “bottom”? I think my bottom is me dying / killing myself. There’s no bottom before that. 🙁
