You might not know what your version of confident looks like yet. But be honest with yourself, and don’t think you have to project a fake societal ideal of “confidence” just because you think people will take you more seriously.
It annoys me whenever I hear about these stupid power struggles between couples where they do these things to keep the “upper hand.” In an attempt to make sure they like you more than you like them, you make them feel like you’re the best they’re ever going to get.
After nine years of being depressed, I still feel like no one really understands me. I think somewhere after the first two years, I started to think no one ever would. So I would distance myself. And then, people understood me even less.
