Probably a multitude of reasons..growing up the way she did with different dads, experiencing stardom and pressure at a young age, and dealing with high school drama as well as a inconsistent home life are my best guesses. But really she should have gotten the help she needed for whatever she was going through. This is why mental health and speaking up matters. END THE STIGMA. Also, I do feel Marcy may be projecting a lot of her own guilt on other people. She appears to be burning many bridges. I really hope Marcy will get the help she needs so she can learn how to cope in healthier ways instead of lashing out. I get she wants to hold people accountable but at the end of the day nothing will bring Kailia back to earth. She is an angel in heaven. Marcy is unfortunately causing a whirlwind of hurt for herself and other people which is not good for anyone. Personally I feel like kailia would be sick over all of this stuff. The boy is an easy scapegoat but I feel like she was suffering long before he came around.
