Sure, emotions are very temporal and frequently changing. But even if I am angry, bored, or excited, I know that I also want to and am capable of being happy. Evenmore, some other emotions are often strongly related to pleasant emotions. E.g. if child gets angry because he/she has to go to bed, it's usually because the child wants to play.
People with depression are not always able to experience happiness. And I cannot explain why, but at the worst, I don't really want to be happy either.
Do you actively not want to be happy, or just not really care about attaining happiness?
This is personally interesting to me. I do not think I am depressed, but I find I do not care much about being happy. I admit the experience is pleasant, but it doesn't bother me that it is rare.
