Adventure Time - All Gummed Up Inside

I can't keep pushing this down any deeper
Why do I keep trying if I can't keep her?
Every move I make is just another mistake
I wonder what it would take
Because it feels like there's a hole inside my body
Like there's a hole inside my heart
It's like this feeling is gonna consume me
If I keep waiting for this thing to start
Oh I feel like I'm all gummed up inside
It's like I'm all gummed up inside
It's like I'm all gummed up insi-I-de
