Past Me vs. Present Me vs. Future Me

Yeah, I get sick of being myself
My immune system, good as it is
It just can't fix that
It's not exactly a physical illness
I'm striking matches now
Had a fun night dancing around familiar faces
Hell, it almost felt like magic
That I turned right into the person I wanted to be
When I was seventeen
Still don't know if that's a good thing
But I know if he met me now
He'd look up to me
He has no idea
On some nights, it still all means nothing
