Tracy's life hangs in the balance later this week as she is diagnosed with a severe kidney infection, which gives her pause for reflection as she drifts in and out of consciousness in hospital.
Ford told The Mirror: "It's a horrible situation and it's definitely life-threatening. Tracy loses consciousness for a few days and the doctors tell Ken and Deirdre to prepare for the worst.
"She is drifting in and out of consciousness and she genuinely thinks she might die. Tracy even says to Deirdre, 'I'm really sorry for all the mistakes I've made and I'm grateful for all the second chances you've given me'."
Asked about Tracy showing her softer side, the actress joked: "It must be all the medication she is on! Tracy does show her vulnerability, but a leopard never changes its spots, so enjoy it while it lasts."
Ford added that she has enjoyed having a quieter time on Coronation Street in recent months.
She said: "I quite like that, actually. More recently the heavier storylines have fallen to characters such as Peter Barlow and Carla Connor, but that can be very tiring and full-on for the actors involved.
"It's nice, as a mum, that I've been quieter. Some weeks I might only be in a couple of days, or not needed at all, so I get to spend more time with my son."
Coronation Street airs Tracy's health scare on Friday (August 10) at 7.30pm and 8.30pm on ITV1. Get the Inside Soap magazine on your iPhone or iPad
