Ok then I'll add an answer to your question in spoilers just in case.

>!In the beginning, the main character is not unhappy, but he can't be said to be happy either: he's just living. He has wants but he doesn't really act on them. He finds the situation all around him to be very strange.!<

>!The common people, socially lower than him, find happiness in their lives, but they're more free than he is in some regards. The people higher than him seem to have it better than him too. !<

>!The most important take you can get from the book, in my opinion, is that when Winston and Julia try to get away from society and become free to build their own happiness, they're denied that. However, in order to have no martyrdom, the regime makes people happy that they will die through brainwashing before killing them. The final lines are about Winston loving Big Brother.!<
