I highly recommend reading up about The Stockdale Paradox. It is incredibly profound and inspiring. It helped put things in perspective for me. Perhaps it is something that you will find to be helpful.
The Stockdale Paradox is named after admiral Jim Stockdale, who was a United States military officer held captive for eight years during the Vietnam War. Stockdale was tortured more than twenty times by his captors, and never had much reason to believe he would survive the prison camp and someday get to see his wife again. And yet, as Stockdale told Collins, he never lost faith during his ordeal.
I copied and pasted the bold text above to give you an idea.
