Randomness does not exist in the universe; we just cannot see all data points that lead up to events.
Wherever you are and whatever you are doing is exactly where you always were going to be, doing as you always would be. This is not fate or prophecy, it is rational.
Take flipping a coin as an example. This is commonly used to determine a random outcome, but at some point, we will have technology that can figure out all factors that determine the outcome before it happens. The force applied to the coin by the thumb, the velocity of the thumb prior to the flip, air resistance, angle, friction of the surface, among countless other necessary data points. With all required data, it would simply be a complex math equation whether it lands heads or tails.
Expand this example to your own life. When you woke up yesterday, was the act of you getting out of bed random? Is it possible there was a series of factors that caused your brain to decide the exact moment to get out of bed?
When you do something that seems random for you, is it possible there are measurable factor that led you to the decision, such as lack of sleep, stress, anxiety, among countless others?
This Determinism philosophy is what many Rationalists believe. If they are right, does it have to be sad? If bad things that happen to us always would have, can we just let go? Can we appreciate and embrace our place in the universe and just enjoy the ride?
