Time and unforeseen circumstance happen to all of us.
There is no plan to life, no fates or guiding angels, life happens.
There is no point in asking why things happen (except in a scientific way!) things just happen.
But that doesn't mean that one should give up, cover oneself in sack-cloth and ashes and run around crying: "Woe is me!"
One should take whatever happens in life and try to move on, however hard that may be.
One can only do what one is able to take the best course from where one is - while trying to effect whatever one can to guide the course of future events.
