How does the increased pressure of running Turtle Island effect Eustace? How is he relating to the people around him?

After Eustace had run Turtle Island for a few years he was still overly stressed. Every kid Eustace taught he thought they were so annoying and he was never truly becoming happy with what he was doing. Something that really increased Eustace's pressure was that he became arrested. He was arrested because the government thought he was killing illegal animals. The government found out because of his neighbor. Due to this Eustace kept having to make deals with his "enemies", which was something he wasn't ever used to doing. He also had to keep worrying about the streets and areas surrounding his camp incase of huge roads or resorts would be established. Also due to his world completely revolving around Turtle Island he started to ignore Valerie, which caused her to cheat on him with one of her friends. This causes Eustace to become depressed because everything is going down hill for him and everyone around him is pulling away from him.
