EastEnders will air a dark storyline for Kat Moon next month as she makes an attempt to take her own life.
The long-standing character, played by Jessie Wallace, reaches her lowest ebb as a devastating build-up of troubles finally take their toll on her mental wellbeing.
Kat has faced a number of personal setbacks over the past year or so, dating back to the moment that she and husband Alfie lost the Queen Vic at Christmas 2013.
Without the pub to rely on, things later became worse for the Moon family as their financial situation deteriorated further. This led to Alfie seeking a reckless solution by committing arson at home in an insurance scam and inadvertently leaving Kat badly burned.
Kat was left humiliated when she and Alfie were forced to squat in an empty flat in Walford as they had nowhere else to stay following the blaze, but the final straw for their relationship came when Alfie's involvement in the fire was finally revealed.
More recently, Kat has also struggled with the revelation that her daughter Zoe wants nothing to do with her, as well as the agonising dilemma of whether to accept money that her abusive uncle Harry Slater left for her in his will.

Upcoming episodes will see Kat discover that her grandmother Mo Harris has accepted Harry's cash on her behalf, which sends her on another downward spiral and leads to her taking an overdose.
Alfie proves to be Kat's saviour as he realises what she has done and races to her rescue, calling an ambulance so that she can be rushed to hospital.
EastEnders bosses have carefully planned the Kat storyline for several months and it was always the case that her current troubles would lead to her terrible decision.
As a mum-of-four with strong family ties, Kat has so much left to live for and the story will see her start to slowly rebuild her life after she survives the suicide attempt.
