"I was in way over my head with the surgeries," Pratt, 29, tells WHO exclusively. "I had no idea what I was getting into or that it was a lifelong commitment. It was very challenging, both physically, emotionally, spiritually, mentally, on my husband and on our lives."
In fact, Pratt, 29, admits, "It was a huge turning point for us in such a negative way. There was a fallout with The Hills and a lot of backlash with the things we were doing. We spent more money and it was so unnecessary. Sometimes I can't believe I did that to us and to me. It's been a lot to overcome."
Still, the reality star says, "I don't want to say I regret it 100 percent because I've tried to grow from it."
In 2013, Pratt underwent breast reduction surgery, removing her size F breast implants.
"They were so heavy they were falling through the skin," she says. "It was just too heavy for my body and I was in pain and uncomfortable all the time. I thought, 'What do I need this big of breasts for?' "
Now healthy and happy, "my priorities have shifted," Pratt says. "I think it's important not to pigeonhole yourself in past mistakes but to learn from them and move on."
