She is now speaking out about the link between her addiction and her then-undiagnosed neurodivergence, and her hope to be an advocate for those in similar situations.
Whanau told Newstalk ZB she was talking with major organisations like Autism New Zealand, which had contacted her to thank her for speaking out.
“I thought I was this really outgoing social butterfly party girl, but really, I drank because I had quite severe social anxiety,” Whanau said.
“I just didn’t want to admit that to myself. I guess that’s the autistic side of myself.
“And the ADHD side, it’s like a dopamine hit. It is like, ‘Oh, I have had a couple of drinks, I feel good, I am just going to chase that buzz’.”
She said after her diagnosis, she no longer craves alcohol as she does not try to “mask or dull” herself.
Royal Australian and New Zealand College of Psychiatrists New Zealand national committee chairman Dr Hiran Thabrew said untreated ADHD was associated with an increased risk of depression, anxiety, accidents and injury, substance abuse, eating disorders and suicide.
Thabrew said early identification and treatment “significantly” improved the lives of people with ADHD.
He said ADHD was “complex” and “often misunderstood”, even among many health professionals.
“Having a comprehensive framework for the identification, diagnosis, treatment and ongoing management is important for lifting the standard of care for people with ADHD right across the board.”
Whanau said having traits of autism also “played quite a big part in making last year challenging”, adding many neurodivergent people also struggled with alcohol problems.
“It’s still something I’m learning about myself. I’ve basically gone 40 years without this diagnosis, and when I look back and think about the assessment, things are fitting into place.”
