Trying to distinguish happiness from all those other feelings is like trying to separate depressed from all the negative things you feel during a day. Some words do not describe specific emotions, but instead indicate a general state which has all kinds of internal variation and magnitudes. A person who doesn't have much financial stress, their kid isn't having issues that require lots of problem solving from the parent, their job is fine, they are not arguing with their spouse regularly. They would say they are happy. Alternately one can have accomplishments , new PR at the gym, solved an issue at work, but still think of themselves as unhappy because they have things that they prioritize more highly that are not going well.
