Jewel has accused her mother of "embezzling" over $100 million (S$133 million) from her.
The 48-year-old singer claimed she realised when she was 34 that she was $3 million in debt and has accused her mom Leandra Carroll of having "stolen" her fortune.
Speaking on the Verywell Mind podcast, she told host and therapist Amy Morin: "Thirty-four years old, I realised I'm $3 million in debt, realised my mom stole it, realised everything I thought my mom was isn't what she was.
"Very difficult psychological thing to come to terms with.
"I didn't realise what my mom was until I was 30-something. I woke up and realised she embezzled all of my money, over $100 million."
Jewel then delved deeper into her familial relationships and soon began to understand that her father hadn't "stolen" her and her three brothers away from their mother.
She continued: "And then as I started investigating the truth about what my mom had told me in my life versus what was true, I realised that pretty much everything I formed my reality on was a fiction.
"For instance, my dad didn't take us away from my mom. He actually did a good thing and didn't steal us. I thought he had stolen us or was blackmailing my mom to not have us... actually realised my mom left us because she didn't want to be a mom.
"Having to go back as a 34-year-old and re-work your psyche was not fun, but so powerful."
The You Were Meant For Me singer praised her father for raising her and her siblings but admitted her upbringing wasn't ideal.
She said: "My dad was this volatile alcoholic who hit me, very easy-to-identify 'bad guy'.
"My mom seemed like the opposite. She was calm, she was soft, she never yelled, obviously never hit me. And I didn't realise I was being abused in another way at the time."
"Let's say I would show up on her doorstep, she would say, 'Your mind is so powerful. Our minds are only tapped, we use, like, one to 10 per cent of our brain power. Our minds are so powerful and I think you, Jewel, are so powerful that I think you could sit here and stare at this light bulb and you might be able to get it to turn off with your mind.'
"That is such an abusive, effed-up thing to say, but I felt so loved. What it actually was, my mom didn't want to stay there and be with me, and she babysat me by having me watch light bulbs. So sometimes the appearance of an attached figure isn't what it seems."
