Nothing happens for a reason. Life is without any inherent meaning.
There is neither a god nor is there fate nor destiny. There is existence, and then there is none. The nature of it is another epistemological conundrum. It is only a depthless and sanctimonious self-importance that ascribes reason and meaning to human existence.
You have to construct your own meaning. And that meaning is buoyed up by mere faith. Faith in its veracity. Beyond that, there is nothing more to it. Zilch.
Can’t you understand this reality?
