After the birth of her son during lockdown, the Welsh actor was flooded by disturbing thoughts she couldn’t shake, a plunge into darkness and isolation. She discusses how it changed her and what helped her recover

Kimberley Nixon’s memoir, She Seems Fine to Me, is out on 7 May, and she’s quite terrified. This isn’t an author worried by sales figures or reviews. Nixon’s book is an up-close-and-personal account of perinatal OCD. It tells of the dark, disturbing thoughts that taunted and haunted her after the birth of her son: her racing mind, relentless rumination, the Technicolor horror stories that played inside her head, always centred on harms to her baby. The book holds nothing back.

“Is it really brave or is it really stupid?” says Nixon. “In my head, I’ve written a book about what a horrible person I was and put it out in the world – and I have to keep reminding myself that’s not it. I’ve written a book about a mental health condition and trying to fight it.”

She’s gone from ‘queen of the soaps’ to Loose Woman known for her outspoken opinions and rockstar son Matty Healy. Now sober, she is enjoying another reinvention

Denise Welch doesn’t seem the kind of woman who would turn up with an entourage. But here she is having her hair primped in a makeshift changing room by two people. One tickling her fringe, the other tweaking her tufts. Blimey, I say, have you got two assistants? She grins. “No. There are three.” And now it turns out she’s got a fourth. I offer to make her a cup of coffee. She warns me she’s fussy. “Three teaspoons of Coffee-Mate, please.”

Welch is having a moment. She calls it, with a fabulously camp flourish, her renaissance. The actor and Loose Women regular has hardly been invisible in recent years. But this is on another level. For most of the 2000s, she has been best known for dishing out blithe opinions about anything and everything, and being the mother of the 1975’s frontman, Matty Healy. Now, though, it’s the acting that’s getting the attention. Earlier this month, she returned to the drama series Waterloo Road as the hopeless French teacher Steph Haydock after a 15‑year absence. This time around, she’s a supply teacher and is even more hopeless. Welch has also got parts in the new Russell T Davies drama series Tip Toe, the Josh Pugh sitcom Stepping Up, both on Channel 4, and the adaptation of Graham Norton’s novel Forever Home.

Study also says almost half have a mental health issue such as anxiety or depression

• How bad is maternal health in Europe, and how can we fix it?

Seven out of 10 mothers in the UK feel overloaded and almost half have a mental health issue such as anxiety or depression, new research has revealed.

The survey of mothers’ experiences in 12 European countries also found that most of those in Britain still do the majority of household tasks and caregiving work alone, and that the UK was among the worst for motherhood disadvantaging a woman’s career.

71% of UK mothers feel overloaded – 4% more than the 67% European average

47% of UK mothers suffer from mental health issues, including burnout, compared with 50% in Europe as a whole

31% of UK respondents felt motherhood had a negative effect on their career, higher than the 27% average, with Ireland the highest on 36%
