The Boomtown Rats singer - who lost his daughter, Peaches Geldof, in April this year to a heroin overdose when she was just 25-years-old - has revealed that their seasonal festivities will be "a lot less" this Christmas.
He said: "It’s been a c**p year. There is no end to it. It is for the rest of my life. I’ll be with the family for Christmas.
"They will make Christmas come alive again. It will be like everybody else’s Christmas but a lot less."
The 63-year-old singer and philanthropist will spend Christmas Day with his grandsons, and Peaches' sons, two-year-old Astala and 19-month-old Phaedra.
Bob also revealed that he "goes over and over and over" what he could have done to help his late daughter in the months leading up to her death.
Meanwhile, he has been channeling his grief and trying to turn it into something positive by helping raise money for the Ebola crisis in West Africa.
Bob organized the recording of a new version of 'Do They Know It's Christmas?', recruiting big-name stars including Ed Sheeran, One Direction and U2's Bono. The song soon became the UK's fastest-selling single of the year.
Speaking about the crisis, he told the Sunday Mirror: "The great tragedy of this filthy disease is that it stops people from touching.
They take an Ebola orphan and they give it to a surviving adult and ask them if they will accept it.
"But they say ‘no.’ The kid has just come out of hospital and they are
asking people to look after it for the rest of your life and they say ‘no.’
"The child is then forced to fend for itself. Their community has been ravaged and out in the provinces they have no real idea how many have really died."
