Depressed or no?

Am I the only person that thinks I'm simply not as happy than others? I wouldn't say I'm depressed, at least not anymore. But other people I know are always smiling, laughing, hanging out with friends, going out etc. The only time I'm happy is when I have food, just got off work, or just got paid. I wonder if everyone else just fakes it like I sometimes do, or if I just don't get joy out of the little things in life? 🤔
