Kat Slater has been slowly falling apart on Albert Square, after suffering money issues and landing in hospital when her husband, Alfie Moon (Shane Richie), attempted to burn down their property for insurance money.
But it seems as if things are going to get even worse for Kat.
The Walford resident, as many fans will know, was sexually abused by her uncle, Harry Slater, when she was just 13 years old, leading to the birth of her eldest daughter, Zoe.
Now, rocked by news he has died and left her money in his will, Kat has been seen struggling with alcohol dependence - not to mention sinking into a depression.
And, in a shocking twist, the mum-of-four is set to try and end her torment by taking an overdose.
A source told the Daily Star: “This is the start of a huge new storyline for Kat. She's been knocked down so many times in life and always gets up. But it will all become too much for her.”
Thankfully, however, Kat’s suicide attempt will be discovered when estranged husband Alfie realises something is terribly wrong.
After hospital staff are able to bring her back around, Kat will be seen going in search of answers about her past.
The source explained: “Once she recovers from the overdose she wants answers about her past. That's where June [Whitfield]’s character comes in. She plays a nun and Kat hopes she'll provide her with the answers she needs."
The BBC have been working closely with the National Association for People Abused in Childhood (NAPAC) to ensure that the storyline is handled sensitively.
A spokesperson for the organisation revealed: “It has been very encouraging for me that the script team at EastEnders has gone to the trouble of contacting an organisation working with adult survivors of sexual abuse to check this storyline and raise awareness of this difficult issue.”
These EastEnders scenes are set to air in April 2015.
