Two mothers from the Anglia region have been sharing their experiences of post-natal depression, in the hope of helping other parents recognise the symptoms.
Kelly Goody, from Framlingham in Suffolk, first became a mother at the age of 35.
It wasn't until the birth of her second son, Lucas, three years later, that she began to struggle.
Beginning with a persistent headache, she at times believed her house was haunted, her elder son Thomas was possessed, and had constant fears about the health of her and her boys.
Marie Miller, from Linton in Cambridgeshire, started to struggle while she was pregnant with her twins John and Max.
Marie and her husband were trying for a baby for four years so, when she finally learned she was pregnant, she expected to be over the moon.
Those emotions were quickly overtaken by feelings of anxiety, inadequacy and a fear she was letting her children down.
