I had this dream last night, so I wrote a song about it. 

A little girl of 12

Had the smarts

Maybe even the looks

But she had a little friend

A little caterpillar

Since she was just a little 5

She found it one day

It seemed friendly

Said it wanted to protect her

From the bad of the world

But her brother saw through

See this little caterpillar

Gained her trust

Sure it seemed good intentioned

But it sat at her ear

Constantly saying

Hey there my friend

I know it might not seem

So plausible yet

But let's question

What if?

What if they hated you?

What if he died?

Oh just take a moment

To think what if

What if they didn't love you?

What if you disappoint him?

Oh I know it's not yet

Plausible to you

But give me a moment

To protect you from everything wrong

Everyday it warned her

And one day

She let it get in her head

It layer its thoughts

All around to shout

Keep her from enjoying

The life she used to enjoy

See these little caterpillars

Had her trust

Sure they seemed good intentioned

But they sat in her head

Constantly screaming

Hey there my friend

I hope it might seem

Plausible just yet

But let's question

What if?

What if you're mean?

What if you died?

Oh please take a moment

To ponder what if

What if they never loved you?

What if you're not worth it?

Oh I know it's starting to yet

Be plausible to you

But give me a moment

To protect you from everyone

The little girl

Let it get inside her head

That these things

These untrue things

Would become the truth

A teen girl of 14

Had the fear

Especially even the doubt

Because she had a little friend

A little caterpillar

Whose name was Anxiety

And I hope one day

To my dear little friend

I'll be able to scream

Hey there my little friend

I know it might not seem

So plausible yet

But let's question

What if?

What if they loved me?

What if he survives?

Oh just take a moment

To think what if

What if they did like me?

What if I make him proud?

Oh I know it's not yet

Plausible to you

But give me a moment

To stop thinking about

Everything wrong

Because my thoughts

Aren't reality

Now matter how much you scream

How much you try to warn

Sometimes what people say

Is really what they think

So pack your bags, Anxiety

Your many legs can carry

The weight of my troubles

All by yourself
