Worthless?

There it is again, that looming feeling of self doubt.
The bitter feeling biting at the very core of my being.
I am smiling, yet, inside screaming.
Wondering, if this melancholy feeling will ever fade?
Will these waves of self doubt ever subside?
Will this insanity inside my mind ever dissipate?
Leaving me to feel free and unrepressed, 
No, this feeling will continue to devour me,
a product of my own anxiety and fears.   
Alone, and I fret this is how it will always be.
Deep down I know my truth worth,
Yet, I am left here drowning in the pain,
unable to contain this angst feeling devouring my soul.
Screaming to my self, you're worthless, worthless, worthless.
I am atrocious, hideous, I am nothing.
I don't deserve anything that I have and I am not worth having.
I only wish to escape these thoughts, the intricate weaving that makes up my mind,
to find my true worth and believe that I am something more, than anyone here could ever hope for.
