I think detaching for me was a difficult concept to grasp. I tend to think of it as not letting someone else's emotional response to something control my feelings or emotions. I don't believe it's the same thing as disconnecting or withdrawal.
I think the GAL'ing for me has been about creating the life for myself I want to live. I am focusing on activities that put an extra spring in my step and that make me feel alive. I am surrounding myself with people with a positive outlook.
