A happy poem?

Trying to pen a happy poem
Is like
Sandpaper on skin
Nothing feels right
Words elude me
Thoughts of joy
Escape my mind
Never reaching my lips
The darkness
I understand
Almost comforting
Like a caterpillar
In its cocoon
Hoping to never emerge
Just stay safe
In its own little world
I don’t want to spread my wings
I don’t have any desire to fly
So I sit
And try to think of the words
I know I should say
And my mind
Is nothing but an empty page
