The most healing thing you can do is to start praising Him always. We have focused on ourselves for too long, dwelt in fears and anxiety. Our thoughts are not filled with Him, except for desperation, and our prayers are not filled with praise, but with panic.
How often during the day do you honestly stop and focus fully on His might and glory? How often during the day do you stop and not think about yourself, but devote yourself fully to praising Him? If you do so, your anxieties, worries, panic and such will cease.
