Knowing all I need to find....

"Home, why am I everywhere but home?
Why do I feel so alone, when everybody's screaming out my name?
I just wanna go home. Pack my bags and hit the road.
Knowing all I need to find is the life I left behind
I just wanna go,
home."

First and foremost, those lyrics are from a song called "Home" by Paradise Fears.

They have been stuck in my head for over a week and I'm beginning to think they mean something. However, I am conflicted as to what they could mean. I am "home". I'm living in the house I have been in since I was 2 years old. If I am "home", why do I feel like these lyrics mean so much?

Is it because I'll be moving about 100miles away in the summer to attend my chosen university and I shouldn't go? Or is it because I don't feel like this house is "home" for me anymore and can't wait to leave?

I'm a firm believer that there is a reason for everything and I'm set on figuring this one out... Help please?
