Real stumper

On the simplest question I'll go blank
The complexities attack my appetite
How can I get out of this
Doesn't feel right
I'm so thick she eats with a fork
I'll be gone
I'm almost gone
I'm gone
Our worst phase on a hot plate
I got you ice cream
It froze your face and you dropped it
I got nothing and it melted
I couldn't be higher you say
I couldn't stay, come with
You bite off my head
You don't know where I bury myself
You never know when I can be behind you
That simple answer is a real stumper
You wait and see when I get behind you
That difficult decision is a real stumper
Wouldn't you say
I couldn't be higher
