Every mountain has a peak and every valley has a low point. Similarly, life has its ups and downs. No one is up all the time or down all the time. Problems do get resolved in the long term. They don't last forever.
History teaches that every problem has a limited life span.
Storms are followed by sunshine. Winter is followed by spring. Your problems will get resolved given enough time. There are two sides to every coin. What may be a problem for one could be interesting opportunity to someone else.
