I feel nothing but a cold knot of anger, and an aching loneliness.

There was a cold knot of fear in the center of my gut.

I ran, ignoring the cold knot of despair her words had punched into me.

Already a cold knot of foreboding twisted inside his heart.

A cold little knot of fear wound together in his stomach.

He felt an old excitement, a cold hard knot of fear in his guts.

Or as pure as she could be with a small cold knot of pain in her heart.

The cold knot of tension in his gut dissolved a little.

He was wide awake now, his stomach in a cold knot.

But even as the questions came into his mind, a cold knot of fear closed on him as he began to suspect the answer.
