There is an odd mental process that can go on here, where someone is so afraid of one thing that they will do the opposite, even though they are fearful of that as well. "If I throw myself over, then I don't have to worry about falling off." That would release one from absolute freedom into the hands of fate. The choice made is not responsible, but the burden of making it has been lifted and the desire for a predetermined destiny has been fulfilled. For some, a bad future that is known is preferable to a future of free choices and individual responsibility.

The original example is from Begrebet Angest (The Concept of Dread), by Kierkegaard.
Haufniensis uses the example of a man standing on the edge of a tall building or cliff. When the man looks over the edge, he experiences a focused fear of falling, but at the same time, the man feels a terrifying impulse to throw himself intentionally off the edge. That experience is anxiety or dread because of our complete freedom to choose to either throw oneself off or to stay put. The mere fact that one has the possibility and freedom to do something, even the most terrifying of possibilities, triggers immense feelings of dread. Haufniensis called this our "dizziness of freedom."Existentialism - Wikipedia
The archetypal example [of existential angst] is the experience one has when standing on a cliff where one not only fears falling off it, but also dreads the possibility of throwing oneself off. In this experience that "nothing is holding me back", one senses the lack of anything that predetermines one to either throw oneself off or to stand still, and one experiences one's own freedom.Dread - New World Encyclopedia
He uses the example of a man who when standing on the edge of a cliff realizes that he could hurl himself over the edge at any moment. In this way, the man recognizes his own intrinsic freedom and the possibility of deciding his own destiny. This recognition triggers a kind of “dizziness of freedom” in which the man becomes aware also of his own responsibility.Bad faith - Wikipedia
Between "a bad future that is known" (suicide) and "a future of free choices and individual responsibility" (authentic living) is living in "bad faith", an inauthentic life. Many people find themselves living here for most of their lives. I believe that if one considers this mental exercise I've outlined above, they could change their perspective on living and reach for an authentic life, the only real choice to be made.
