Kerry Katona's anxiety goes "through the roof" when she binges on alcohol.
The former Atomic Kitten star - who has battled substance abuse in the past - tries to avoid drinking booze because it makes her anxious and depressed.
Writing in her new! magazine column, she said: "I'm not a big drinker, but when I do drink on special occasions, it does heighten my anxiety.
"I went to Thailand with the kids three years ago and I was drinking non-stop for a week.
"My anxiety was through the roof.
"Alcohol is a depressant and because I am so prone to anxiety and depression, I can't do it.
"And I'd definitely never touch drugs again.
"I can't even imagine what I'd feel like."
Meanwhile, Kerry recently shared the harrowing story of how her late ex-husband had planned to "inject" their daughter with heroin before taking his own life.
Kerry believes she made the right decision when she took out a restraining order against George Kay - who died in 2019 from an overdose at the age of 39 - because she was terrified of what he could do to her and her family, including their little girl Dylan-Jorge, now eight.
She said: “We were on FaceTime and DJ wouldn’t speak to him, she was only three at the time, and you know what kids are like. He was threatening us both and then he said to me, ‘How’s your mum, Kerry? Is she alright?’ before winking and ending the call.
“It really scared me. Before that, he had threatened to rape my mum and slash her up in front of me. So I didn’t know what he was going to do next. I was terrified he was going to hurt her or DJ.”
And she wrote in her book, 'Kerry Katona: Whole Again - Love, Life and Me': “[After George died], one of his friends came round and told me I’d done the right thing in keeping him away from DJ,” she writes.
“Apparently, he’d planned on injecting her with heroin and then killing himself.”
The 42-year-old star - who also has Molly, 21, and Lilly, 19, with first husband Brian McFadden and Heidi, 15, and 14-year-old Max from her marriage to Mark Croft - claimed George's family haven't been in contact since he died and she has no idea where his grave is.
Although George died three years ago, Kerry still feels "scared" he's going to "get" her and doesn't believe she'd be alive today if he hadn't passed away.
