Catholic blogger and author Michael H. Brown posted this message recently on his website Spirit Daily. It bears repeating:
For Satan is a supreme liar, and will whisper into your ears discouragement, disparagement, false notion, umbrage, anger, false memory, exaggeration. He can also make you hear something other than what a person is saying.
As far as anxiety, that’s a form of fear. The devil makes you dread for the future, for your job, for your health, and for your family; and especially he wants you to fear him. He wants you afraid because his minions are parasites; they use fear to energize and materialize their disembodied existence; they revel in and feed off anxiety, anger, and fear.
This doesn't mean we have to go around with smiles pasted on our faces at all times. I know this would be hard for me, given my personality.
But we can at least be mindful that choosing gloom and doom isn’t what God wants for us. We have a choice. We can choose to walk out from under the black cloud and into His light. We can choose to be what we’re called to be: joyful children of God.
