Here is a gem from Henri Nouwen’s The Inner Voice of Love: A Journey from Anguish to Freedom:
It can be discouraging to discover how quickly you lose your inner peace. Someone who happens to enter your life can suddenly create restlessness and anxiety in you. Sometimes this feeling is there before you fully realize it. You thought you were centered; you thought you could trust yourself; you thought you could stay with God. But then someone you do not even know intimately makes you feel insecure. You ask yourself whether you are loved or not, and that stranger becomes the criterion. Thus you start feeling disillusioned by your own reaction.
Don’t whip yourself for your lack of spiritual progress. If you do, you will easily be pulled even further away from your center. You will damage yourself and make it more difficult to come home again. It is obviously good not to act on your sudden emotions. But you don’t have to repress them, either. You can acknowledge them and let them pass by. In a certain sense, you have to befriend them so that you do not become their victim.
The way to “victory” is not in trying to overcome our dispiriting emotions directly but in building a proper sense of safety and at-homeness and a more incarnate knowledge that you are deeply loved. Then, little by little, you will stop giving so much power to strangers.
Don’t be discouraged. Be sure that God will truly fulfill all your needs. Keep remembering that. It will help you not to expect that fulfillment from people who you already know are incapable of giving it.
