Final answer:
Consolation and indispensable are the words used to describe seeking comfort in difficult times and the necessity of something.
Step-by-step explanation:
Consolation: When someone is feeling sad or upset, they may seek consolation from others for comfort and support. For example, a friend might say, "I'm here for you, and I'm sorry you're feeling this way. Is there anything I can do to help?"
Indispensable: An indispensable item or person is one that is absolutely necessary and cannot be done without. For instance, a computer is indispensable for many people in their daily lives because they need it for work, communication, and entertainment.
