Heart Attack

I think this song can have a couple meanings, depending on how you look at it.

One (not as likely of a meaning) is about a girl who tends to fall for troublemakers and guys that end up being horrible for her.They're the kind that want her to become what THEY want her to be, by telling them what to wear, how to have their hair styled, how they act, etc. They don't respect her the way she should be respected. Even though she's comfortable around other guys and has no problem playing with their emotions a tiny bit when she doesn't have affectionate feelings towards them, as soon as the guy she's feeling for is around, she doesn't know what to do, is afraid to do anything, and just freezes. She's afraid of speaking up, fearing that something horrible would happen (as many girls in this situation would feel). She feels that this is happening again with her newest guy, and she decides to put her foot down and prevent herself from falling for the same trap. She tries to speak up and be her own self, but he thinks she wants more of his attention, and it comes out all wrong. She hates feeling that way, but she likes being attended to, being 'cared' for, even if it's for the guy's benefit. She's determined not to fall in love with the guy though, because she knows it'll be doomed, seeing how he's treating her. She knows that she's the one that usually makes the mistake of staying with these losers, so she's trying to abstain from her usual routine. *Again, not the likely meaning, but it could be interpreted as such to some

The second meaning that I feel is more accurate is more simple. It's about a girl who loves to tease guys, mess around with their heads a little bit and doesn't have trouble being around them. She starts having feelings for a guy in particular, and it scares her a bit. She wants to dress up, gussy herself up and be more womanly for him, and wants to impress him. She starts feeling nervous and giddy around him, and when she tries to play it off and be her typical self, it backfires and she falls all over him. She hates feeling so defenseless like that, so she's trying her best to keep her distance and not fall for him. She seems like she's never been in love before, or that she HAS, but has been burned badly, and never wants to be hurt again. As the song keeps going though, she's feeling less and less able to contain herself, and eventually she can't help it anymore (I'm flying too close to the sun, and I burst into flames), and she's at her breaking point. I also get a sense though that she wants it all to happen a little bit, but she's terrified that her mind will end up backing out of the relationship, and that she's "scared she'll take off in a run" and screw it up. We don't know if she finally gives in, but we sense that she can't take anymore temptation. All we know is that if she indeed falls for him, she'll feel as though she's having a heart attack, too overcome with emotion, defenselessness, passion and fear all at once.

^ Again, those are MY two possible interpretations. The latter of the two is one I personally believe in more, but they both can work with this song.
