“I don’t think anything can prepare you for becoming a parent; I was overwhelmed with the responsibility of it,” she told Mamamia.
The New South Wales mother said she quickly became extremely tired, anxious and unable to complete tasks.
“My baby slept for 16 hours a day, but I was utterly exhausted,” she said.
“I felt like I was just being sucked into a black hole. I didn’t want to go out and share my baby and I didn’t want people to come to me.
“I just felt like I was in a tunnel and I couldn’t get to the end – everything was just overwhelming and I was in a constant state of misery.”
But Alison kept her feelings close to her chest, managing to fool her friends, family and husband for months.
And if you followed her on social media, you would never have known there was anything wrong.
“I had my show face on for social media,” she said.
“I felt the need to post a happy family photo when I was absolutely in pieces.”
“I felt I just had to say, ‘I’m a happy smiling mum and here’s my baby and everything’s OK’, rather than calling someone and saying, ‘I’m not OK’.”
She said there was one particular photo that came to mind, which she even edited before posting.
“I just felt so depressed. When the baby went to sleep I’d sit on the bathroom floor and cry, but I needed the photo on there,” she said.
