To most people, Leo seems like the most confident person in the room. But everyone has secret vulnerabilities. We're all human. And Leos definitely have an insecure side - they are just better at masking it than others!
Your sign needs to be appreciated for your talents - explicitly. If that doesn't happen, you begin to worry that maybe you're not as great as you think you are. Perhaps your friends and romantic partners aren't what they seem. No need to be paranoid about it. Everyone still loves you!
By owning your vulnerability, you make yourself even more relatable to people, if that's even possible. No need to hide what may be one of your most precious qualities.
