Gone Away in Edna's Goldfish

Where did my friends go?
They went so far away
I asked them why but they said they could not stay
But when they came back I noticed that my friends had changed

I was up so high
with my feelings but I fell back to the floor
And when I came to I noticed, that my friend's they
wanted nothing more to do with me...

Why have I gone away?
Why did I go away?
