The 33-year-old TV star, who's best known for her role as Rosie Webster in Coronation Street, shared the news on Instagram, after a couple of months away from social media.

She said she was left "emotionally struggling" after splitting from the father of her children, footballer Scott Sinclair - with whom she shares Matilda, seven, Delilah, five, and Charlie, two.

She also explained her reason for pulling out of a theatre tour of Cluedo 2 which kicked off last month, saying it was due to a bad reaction to her medication for attention deficit hyperactivity disorder (ADHD).

At the time, it was announced that Flanagan had withdrawn from the show for "medical reasons".

Alongside a selfie with her giving the peace sign, she wrote: "Had a few months off from social but I'm back now.

"So basically I really struggled mental health wise December/January. I felt really not great in my head over Christmas and I didn't really feel that much different when I took the kids away for new year.

"I had a lot of difficult things going on things I just can't talk about on Instagram.

"I felt terrible, so I was due my theatre tour which I was excited about so when I came back from holiday I thought it was best for me to take some medication so I'd feel better and be able to cope better with being a working single mum of three and I was emotionally struggling with the break up from the father of my kids."

'I just love my kids so much'

She added: "I had a really bad reaction though to the medication (an ADHD medication) and it sent me into a psychosis for a few days which I didn't know I was in.

"I just love my kids so much, this bad reaction though was a few days before rehearsals were starting and sadly I just wasn't mentally well enough to do it.

"I was heartbroken as I've always been professional as an actress but I needed to stay at home and feel better for me and my kids, with the help of my amazing parents."

She added that she felt like she was in a "really good happy place" and has found therapy "amazing".

She said: "I feel like I've worked on myself with things that were quite tough to me but I feel lighter now."

Flanagan was replaced in the role of Miss Scarlett in Cluedo 2 by Strictly Come Dancing winner Ellie Leach, who was one of the fellow celebrities to comment on Flanagan's post, writing "love you" with three kisses.

Other stars including Ex-Girls Aloud singer Nadine Coyle, presenter Carol Vorderman and Coronation Street actresses Lucy Fallon and Brooke Vincent also showed their support.

Flanagan played Rosie Webster in the Manchester-based ITV soap from 2000 to 2012, returning to the role between 2017 and 2018.
