“In the midst of winter, I finally learned that there was in me an invincible summer.” ~Albert Camus
About ten years ago, I stopped sleeping. It started on a vacation. The first night in this lovely beach rental, I couldn't fall asleep and stayed wide awake all night.
Of course I was a mess the next day, and the following night I was panicky that I wouldn't be able to fall asleep again.
This was the start of a spiral of insomnia, that led to anxiety about not sleeping, that led to total exhaustion, that led to strange physical symptoms, that caused more anxiety and worry.
