Melanie Hill, who plays Cathy, recently revealed how her character is feeling at this tough time.
She said: "Cathy really isn't coping. She goes into hiding and she is pushing the one person who is trying to help her away. Her state of mind has been affected by what is happening all around her. She doesn't want anyone else to get hurt by what is happening to her.
"We haven't really touched much on her hoarding for a while, but it is good to show that we haven't forgotten. When she is affected by what is going on, she does start to show signs that the hoarding and the worrying is coming back.
