My mums real mum left her and her sister when my mum was a baby and her sister was 3 yrs. No one in the family ever discussed it and my mum was adopted within the family.
To this day it haunts her and, although she doesn't talk much about it, I know it breaks her heart not to know why. She had 3 kids of her own and now grandchildren and every year on her birthday I know she wonders if her mum is thinking of her.
She didn't even want to try to trace her because she doesn't feel she has the right to since she was the one who was left.
I wonder if the poor woman had PND and felt like a freak and felt she had no choice..... We don't even know if she's alive.
