Oh my God, talk about hormonal, I've been having the craziest highs and lows. One day I'd feel like a zombie, and the next I'm totally euphoric and can't stop grinning like an idiot.
Sorry, I digress 
That's perfectly normal if you're female
and a teenager.
There's this really hot girl, I think she was on Star Trek but I can't remember her name.
The body, yeah, but the name escapes me.
