The spirit of God inclines us to fervor, but this fervor is calm and causes no trouble either to ourselves or to others; when it meets with obstacles it knows how to stop and submit to God's will. Its only arms are patience and gentleness. You want to be a martyr; you have a daily martyrdom which you endure unwillingly and without resignation! I see nothing reasonable in such a desire and nothing which looks like an inspiration.
St. Claude de la Colombiere
Since anxiety is so constant to me, it's difficult for me to realize that fervor isn't anxious or troublesome, but is calm.
