Anxiety is a demonic spirit. And, obviously, that means it’s not a good thing at all.
Philippians 4:6-7 NIV
 Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.  And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Don’t be anxious about anything.
Yet, you and I know that’s easier said than done. The demon of anxiety lays its grip on our hearts every now and then, causing sadness and panic attacks.
To be free from anxieties, worries, depression, or panic attacks, you need the help of the Holy Spirit.
And the key to that is to get on your knees and admit your worries and anxieties to Him. Then remain on your knees, and keep admitting your anxieties to Him until His peace takes over your heart.
