I actually made a list of these the week after H moved out and posted it on my kitchen wall (underneath the list of hard truths I needed to know). For a month, I stood in front of this list twice a day and read it out loud to myself. I still do that sometimes when I need the pick-me up. An edited list:
I'm a strong person.
I'm a good mother.
I cherish my friends and family.
I'm responsible for my own happiness.
I'm silly and I can make people smile.
I'm honest and have strong ethics.
I'm an excellent project manager.
I'm easily entertained.
