A reader writes to author Annie Lane about her struggle with self-control and finding that Instagram has taken over her life, becoming a constant distraction. She finds it easier to check on her phone than checking the weather or answering a text, but can lose 30 minutes without even standing up. She has tried deleting the app but re-downloads it and setting time limits, but always manages to override them. The author suggests starting slow, placing Instagram in a folder on the last screen, removing notifications and choosing two short check-in windows a day. If you continue to slip, this is not an excuse for self-destructive behavior. Instead, talk to a friend or a therapist about how to change, but acknowledge the difficulty of coping with this habit.
