Love

One of the reasons Guy is questioning himself and things is because everyone needs love in their lives. No one talks to him and he feels alone. This is why he is questioning himself, his decisions, his life choices, and his ability to make decisions. If you do not have love and the encouragement of others, you will start questioning yourself. You can see that there are people in the book who do not care for each other. At the end Guy finds a group that cares about him. He is with that group now and has the love he needs to be happy and confident.
