Sheridan Smith has said she is "finally in a good place" after struggling with her mental health and misdiagnosis.

The multi-talented British actress has enjoyed great success on TV, film and stage but hit the headlines when she pulled out of a number of shows for a West End production of the musical Funny Girl, later saying she "just couldn't continue - I lost my mind".

The 37-year-old has now told BBC Breakfast that she was wrongly diagnosed for many years.

Smith, who also plays a mother struggling with schizophrenia in a new film, revealed on the show: "It's taken me years to get to a place where I felt like I could own it and then say it. It was speculated that I was struggling.

"There were different doctors giving me different medication but I'm finally in a good place.

"It did take a massive thing to come out and actually say 'I'm struggling and I need help', so I understand that it is hard for people."

Asked what helped her most, she said: "Eventually, I opened up to family members and people could see as well that I was gradually declining and struggling.

"Eventually, after years of going on different medication and just being wrongly diagnosed, I've got the right doctor now and I'm in a great place. It's perseverance but you do get there."

Smith stars in 1980s-set film The More You Ignore Me, penned by comedian and former psychiatric nurse Jo Brand.

"It's a very hot topic [mental health] at the moment and a very important topic so I'm thrilled to be part of it," she said. "We have come a long way [but] I think we can go further."
