I have recently (very recently) become a mother. I am a 48 year old, single woman and have adopted a preschool age child.
With thrilling anticipation, I have worked tirelessly for this for years and nobody is more surprised at the reaction I've had to being a mother than I am.
Almost immediately, a depression washed over me. Not a disabling depression but an old, familiar disheartening, sickening, joy robbing depression.
