What is my life?
My life is the story of my life - i.e., the story I tell about my life. (It is also the story that others tell about my life, but I'll leave that complicating factor for another day.)
Psychology allows me to add subtlety and nuance to my story, and allows me to include parts of the past in ways that otherwise wouldn't make sense.
Psychotherapy allows me look at the scarier parts of the story without getting too scared by them.
