She is asking Santa to tell her if the guy she likes is really going to be with her long term, or if he is going to leave her after sex. She is telling him to help her out because she doesn't want to fall in love again after her heartbreaks with previous guys. I am convinced that she is singing about Big Sean, her current boyfriend as of December 2014. She wants to know if he really likes her or if he is just using her to get over his break up with Naya Rivera, or if he just wants sex. Read more →

All the hurt, all the lies, all the tears that they cry This is saying that people torment them so much that it bothers them and they cry and are sad.
When the moment is just right
You'll see fire in his eyes This means that he will get stronger because of the pain.

The “play pretend” is the world she inhabits while high. By characterizing her high(s) in a child-like manner (“play[ing] pretend”, the “playgrounds” mentioned in verse 2, and endless “fun” are stereotypical juvenile desires), the narrator subliminally conveys a realization of the immaturity of her actions.
When she says Can't go home again shes saying she can't go home, although she is having fun, she still misses the guy she is talking about in the song and someone needs to numb her pain.

She's trying to say that you have to be yourself because, people like you by who you are. It doesn't matter if your fat or skinny someone in the world loves you because you are who you are. And if you don't like me by who I am than you can move along and find a girl who you like because, I am not gonna act like someone I'm not. Read more →

This is about people who live in poverty dreaming about fortune and fame. They wake up, living in a mess, and dream of swinging from the chandeliers, which is a metaphor for the freedom from poverty, not knowing what fame is really like. This sounds a lot like a song for suicide to me. She is sad and ashamed about being used and a "party girl". Later in the song she asks for help and says she is just holding on for the night. Swing from Chandelier can mean hang herself too.
