WATCH: Lauren Young reveals her issue with sister Megan in tell-all video

Lauren Young gets real in her latest YouTube upload where she talked about her personal problems such as her debt, negative attitude, body image, and her relationship with her older sister, Megan.

In the video, Lauren admitted that she used to have a sour attitude on set which led to some of her colleagues to have a negative opinion of her.

"I had a job but my career wasn't at its peak. I didn't realize that I was capable of doing so much more in a professional sense. That was when I realized 'Oh yeah, I'm getting work but am I someone that people want to work with?' That's when it was brought to my attention that no, I'm not.

"Because I thought I was being funny but actually I was being such a brat on set, I was being a diva. I thought I had the right to ask for certain things and treat people a certain way just because I was the actor on set.

"I was always making reklamo, I was always bitching. I was just so demanding and judgmental towards my peers that I realized I was the negative person on the set and that maybe I was the person that they didn't wanna work with.

"That was the first thing that I decided to change. I decided to change my professionalism and if I channeled a better personality and a better work environment, then maybe my acting would be much better and my work environment would become easier," she said.

Another issue Lauren raised is her relationship with her older sister, Megan, when they started to live together in one condo.

According to her, "I thought my sister and I had a great relationship prior to me moving in. And then when we were actually living together, that's when I realized, 'Oh my God, we don't even know each other!'

"It was one of the saddest days of my life. I would walk out of my room and she would walk out of her room and we would treat each other like colleagues, my own sister that I used to live with.

"And it wasn't because of her, it was because of me because of all the negativity in my life, I decided to shun my family out. I thought I didn't need them. That's when I realized, that's the time I needed my family the most.

"I really worked hard to have a relationship with my sister. And you know, she was the one who really helped me out, her and Mikael [Daez], my brother, and my mom.

"They made me realize, it's like a pyramid. Everything you want is at the bottom and everything you need is kinda in the middle, but everything on top is how you're gonna get all of that. So they're like 'How are you gonna get everything in the middle and the bottom if you don't work on the thing that's most essential which is on top?' So that is something that I'm working with now, which is myself."
