I can do it with a broken heart

"Cause I'm a real tough kid, I can handle my shit. They said babe you gotta fake it till you make it and I did. Lights camera bitch smile, even when you wanna die"

.......

"Breaking down I hit the floor. All the pieces of me shattered as the crowd was chanting more. I was grinning like I'm winning, I was hitting my marks"

.......

"Cause I can do it with a broken heart"

........

"I'm so depressed I act like it's my birthday....everyday. I cry a lot but I am so productive, it's an art"

........

"Cause I'm miserable. And no one even knows..."

......

All of this... it's all descriptions of Moranas life. Getting told that she was cursed as a child, getting discriminated, and then that lead to abandonment. Carrying all that sorrow, hatred, and misery with her. Maybe it was not just her heart that was broken, it was her whole world. Then she finds Camp Half Blood, where she tries to hind it all using anger and humor. That works for a while, but then this new kid, so called Percy Jackson shows up. And to put it literally, it all goes to shit
