Fans of the drama series were left weeping into their tissues after last night's (04.03.18) emotional episode when well-loved nurse Barbara Hereward - played by Charlotte - sadly died from septicaemia, but the 28-year-old actress has admitted she had no choice but to leave because she didn't want to get too "comfortable."

She said: "Barbara's had such a good journey, this feels like a good time to go before I become too complacent. That was my biggest fear - of getting so comfortable that I was taking the job for granted. I love the show, I love everyone I work with - there's no negative reason behind why I'm going."

But it won't be the last time viewers see Charlotte on screen as she has admitted she's hoping to bag herself a new role in a different television show in the future.

Speaking to the Daily Mirror newspaper, she said: "I've been locked in to three different shows for about five years, which is so lucky and amazing. But there was a possibility I could try new things and I thought, when will be the right time to go?"

And 'Call the Midwife' will no doubt be a job that Charlotte will remember forever as she has admitted filming the traumatic death scenes made her think about her life.

She explained: "You're representing the trauma that people have gone through. I'm not actually dying, but it doesn't stop me from having the thoughts - what would it be like? It was strange. I did have a sort of existential crisis."

But, although it was difficult to shoot, she's glad she was given a big exit storyline.

She said: "The show has never been one for pretending that the world is somehow rose-tinted. I think to have a character go through this and not survive at such a young age is really mirroring what life is really like. It's tragic, but it's true."
