In a final interview the TV presenter, 25, who died last Monday, said it was through being a mother that she had reconciled herself with her memories of her mother, Paula Yates, who died in 2000 at 41 from an accidental heroin overdose.
Ms Geldof was found at her home in Wrotham, Kent. Police said her death is being treated as a "non-suspicious, unexplained sudden death".
A post-mortem examination proved inconclusive, prompting further investigations. Any inquest is not expected to be opened and adjourned by the coroner until after the results of toxicology tests.
In an interview for Aga Living Magazine, published in the Sunday Times, Ms Geldof said she felt her mother was "living through me all the time because we are just so similar". She said: "I'm not sure I've yet fully made peace with my childhood, but with my mum I have come to terms with everything.
"She had a really difficult time. There are so many parallels between us. Now I can understand everything." She added: "Now I am a mum, I can correct those awful parts of my childhood. It's a really healing process. "
