Fear.

God never said "Don't worry...because nothing will go wrong..."
He said, 

"Do not fear, for I am with you;

Do not be dismayed, for I am your God.

I will strengthen you and help you.

I will uphold you with my righteous right hand." ~Isaiah 41:10

Letting go of our fears doesn't mean they won't come true. 


It means believing the fact that even if our fears come true, 

God will walk with us through everything.
