The 22-year-old aspiring singer passed away in July, six months after being found unconscious in a bathtub at her home in Atlanta, and Bobby says his daughter is now looking down on him from heaven.
He told WBLS' Déjà Vu: ''I've gained another angel to carry me through. I'm really blessed with my children and everything that I have to do is about that.
''It's about love. I have a lot of love around me and have a lot of love that I give. It's about that.''
Since Bobbi Kristina's death, her father has been working on his memoir 'My Prerogative', which he says has been therapeutic.
He explained: ''We've been working hard on it and I'm just trying to get all the cobwebs out and trying to be as honest as possible.
''My story is really deep, but it's funny and it's a whole bunch of things. You can also find some sad parts and some crazy parts, but at the same time it's still Bobby. From my memoirs I'm doing a script for my movie, so hopefully you'll see me on the screen really soon.''
