"Bad things do happen; how I respond to them defines my character and the quality of my life. I can choose to sit in perpetual sadness, immobilized by the gravity of my loss, or I can choose to rise from the pain and treasure the most precious gift I have - life itself." ~ Walter Anderson
In life, we have wins and losses.
A loss is a loss...
A loss of something, someone or some opportunity.
Absolutely, mourn that loss.
Move to being grateful for what you had and at peace with what you do not.
Appreciate each person, thing, and experience for what is given...not what is taken away.
And while you will still have a loss, you will know that you won in the end with your perspective and gratitude.
