Explain lyrics

I can't explain
Everyone keeps saying
Same thing
You must be sad

I guess I'll tell you
It's not the same thing
It took a while but I'm doing ok

We played a long time
We got along fine
And just like you I can't believe it's through.

Believe it.

Me and you.

I'm on my own now
I play alone now
I'd like to say that I'm kind of scared

What if I lose it
I've been known to panic
I make myself sick 'cause I've got bad nerves

I've got bad nerves.

Oh my nerves.
