I don't know

I can’t write a happy song
I’m not happy. Why?
I don’t know
My heart is crying
My brain isn’t growing
I forgot about me
What’s my name?
People make me sad
I’m not happy. Why?
I don’t know
I try to do
I try to live
I forgot who I am
Who am I?
A shiny-shy person
I’m not happy. Why?
I don’t know
I think a thing
I don’t think a lot
I just do this
Isn’t good?
Smiles and screams
I’m not happy. Why?
I don’t know
Want to know
If I’m sick
I think I’m
Am I?
I don’t know
