But you're presuming that mostly suicidal is an nonfunctional mode. If a person has been depressed for 15 years, held loaded weapons to their head while they cried, and have a good way to kill themselves, it's good to be good doesn't matter. If that person doesn't care about longevity, but hopes for a fast death soon, meh. There is no meaning. Especially when you have only one drive, a fast death.
What you are describing is the broader context of innate drive for something. Meaning is a feeling you get from satisfying certain (not all) drives.
