I'm terrified

Another day is passing by
And one more time, the sun will set
I weren't touched by light today

Cars are passing by
People are living their lives
While I'm locked up in myself
What am I afraid of?

Spring is coming
Winter is fading
But how do I spend my time?

Headaches and chest pains
Depression and anxiety
Why am I so damn sad?

Have I been bad?

And the wind bites me
The sun pains my eyes
But I can't live through a window

Why do I feel that I'm not ready for this world
I already faced troubles
We overcame, who can I blame?
Except. For. Me.

Spring is coming
Winter is fading
But how do I spend my life?

What makes me so afraid?
IS life that cruel?
I'm terrified.
