The word "destinying" doesn't actually exist in the English language. However, there are several alternatives you could use to convey a similar meaning. One option is the verb "fate," which means to be predetermined or destined to happen. Another is "preordain," which means to determine or decree beforehand. "Determine" and "decide" are also good options, as they both imply a sense of control over one's future. Finally, "foreordain" is another powerful synonym that conveys a sense of an inevitable future that has already been decided upon. While "destinying" may not be a real word, there are still plenty of effective ways to communicate the same idea.
