Young Lions - Anxiety

I can feel
Something pushing outside in
I have to let it have its way
And sink into my skin

I can feel
Something feeding all my fears
Reminds me I'm alone out here
In this great divide

Oh, I can feel
Something pushing outside in
I have to let it have its way
And sink into my skin

I can feel
Something feeding all my fears
Reminds me I'm alone out here
In this great divide

What's the meaning of my mind?
