Below is an excerpt from Psalm 86 that can be prayed when in such a situation, crying out to God for help when the anxieties of this world threaten to overwhelm us.
Incline your ear, Lord, and answer me,
for I am poor and oppressed.
Preserve my life, for I am devoted;
ave your servant who trusts in you.
You are my God; be gracious to me, Lord;
to you I call all the day.
Gladden the soul of your servant;
to you, Lord, I lift up my soul.
Lord, you are good and forgiving,
most merciful to all who call on you.
Lord, hear my prayer;
listen to my cry for help.
On the day of my distress I call to you,
for you will answer me.
I will praise you with all my heart,
glorify your name forever, Lord my God.
Your mercy to me is great;
you have rescued me from the depths of Sheol.
O God, the arrogant have risen against me;
a ruthless band has sought my life;
to you they pay no heed.
But you, Lord, are a compassionate and gracious God,
slow to anger, abounding in mercy and truth.
Turn to me, be gracious to me;
give your strength to your servant;
save the son of your handmaid.
Give me a sign of your favor:
make my enemies see, to their confusion,
that you, Lord, help and comfort me.
