Kenyа lоcks the dооr ten times аfter coming inside becаuse she fears an intrusion. She recently started working with a therapist to discuss this fear, evaluate and rank its severity, and practice imagining ways to tolerate the distress she feels when she doesn’t check the locks. Eventually Kenya performed exercises where she kept the doors unlocked without going near the door and started learning strategies to cope with the distress.
