Anxiety, I’ve come to realize, is a very expensive habit. It has cost me so much. A lot of misery, a lot of frustration, countless hours of sleep. It’s caused me to miss out on a lot of things that are important to me. How many family dinners have I ruined by letting my mind wander to what could go wrong? How many minutes of vacations have I missed out on because I was preoccupied, lost in spirals about things that hadn’t happened? How many opportunities have I passed up because I was too caught up in my own fears? How many nights did I waste lying awake at night, worrying about what might or might not happen?
