Evidently anxiety is not a new problem. Some Biblical remedies for anxiety are:
Prayer is a well practised stress reliever. It turns the mind from the problem but don't think that God will magically change the situation. Often, there is work to do. Prayer can strengthen the heart to find solutions.
Thankfulness is a reminder of the blessings in our lives. It removes the desire to complain about the circumstances.
The mind is powerful but needs to be protected from constant negativity. Your body will reacte to whatever it is told.
God's advice is trustworthy. Faith is the trust a patient has for their doctor.
Today, I am the patient, trusting in the goodness of God to heal me. Faith is built through the trials of life.
"I will lift up mine eyes unto the hills, from whence cometh my help.
My help cometh from the Lord, which made heaven and earth."
