I am pretty sure this is about someone who is just coming into adulthood and is finally stepping into the real world. It is nothing as they had expected when they were young and now that the time has come for them to go out on their own they are a little bit confused as to what to do with they're life. Being confused they decide to take whatever comes to them, they don't like this but they are scared to actually go for what they think they want because they may not want it later.

Pretty good interpretation for a 15 year old eh?
