The transgender reality TV star, 66, who was known as Bruce before her gender transition, said embracing her true self hasn't always been easy, reported Femalefirst.
"Bruce was a good person who did a lot of good in his life, who had an absolutely amazing life, with wonderful children. When you get name changed, gender marker changed, all that kind of stuff, you know it's the right thing to do in your heart but sometimes I did feel like I was throwing him out. And that was tough.
Caitlyn said she "downplayed" her desire to transition to her former wife Kris Jenner.
"I thought I was probably very honest with her at the beginning. Now did I probably downplay it? Absolutely. Did I ever think eventually it would come to where I am today? No. But we had 23 great years together, and she's a great person.
