"There was a time where my sister asked me, of her trust and will, if I would be the person who assured that her boys got what they needed.
"Whether she's in a conservatorship or not, that was a very normal thing, I thought."
She then talked more about her role in the actual conservatorship and how she played no part in it, as she added: "Once I realized that she's in a conservatorship, I felt like I just didn't want to be a part of it until she was out of the conservatorship.
"There was no me overseeing funds or something like that, and if that was, then it was a misunderstanding. But either way, I took no steps to be a part of it."

"I even spoke to her [previous] legal team, and that did not end well in my favor. So I did take the steps, but how many times can I...well, she has to walk through the door."
Jamie referenced the interview with a still of the conversation on her Instagram, writing: "It's scary to be so openly vulnerable for the first time in my life, but this is MY TRUTH and MY STORY.
