In 2004 she married Jack Sugden and in 2015 she ended up losing her sister Val, who died after a helicopter crashed into the village while the sisters were in the mirror maze.
More recently Diane helped her ex lover Eric Pollard run the B&B.
Soon Diane will be packing her suitcases and leaving her life in the village behind.
Emmerdale: Elizabeth Estensen speaks about her decision to leave
Speaking about her decision to leave the show, Elizabeth said: “For he past 22 years I have loved playing Diane Sugden – she’s kind, reliable and fiercely loyal.
“However, I feel the time has come to say goodbye. Emmerdale will always remain special to me.
“I’ve been treated with respect and kindness and I’ve had the very best friends and colleagues, both past and present. I’ll miss everyone dearly.”
John Whiston, Managing Director of Continuing Drama and Head of ITV North said: “For 22 years, Liz has shone through the screen and into our living rooms as the natural heart and centre of the Sugden family.
“It’s a role she has made so totally her own, bringing compassion, humour and credibility to her portrayal of Diane.
Whenever she’s on-screen, as a viewer, you just let out a contented sigh and say to yourself ‘The Queen is on her throne and all is well with the world.’
“And off screen, you don’t get to stay in a soap that long unless you are a truly professional actor and really, really lovely person. Liz is both.”
Although Liz has now filmed her final scenes, she will be on-screen for a number of weeks.
Emmerdale usually airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
