Dread

Why do these thoughts keep attacking me?
Making me question are things really as they seem.
Of what origin do they stem from,
They fail to cease continuing to come.
Why do they repetitively plague my mind?
Please erase them quickly this time.
Sleep is what I crave right now,
But this overthinking will not stop so tell me how?
Do I gain some peace in my frazzled head?
Instead of living in this space of dread.
