You are just nervous. And it's not necessarily a bad thing - most normal people get nervous, and smart people typically start understanding just how much they don't know which causes even more nervousness. I was much the same, until I realized just how many people make broad claims like they are objectively right, especially on HN. It's not an insult, but more of presenting opinions as fact ("microservices are bad", "java sucks", "the best way to do x is y"). So, it made me feel better to just speak to what I know as if it's the truth, just like other folks do. I don't wonder if I'm giving a good answer, I speak as if I'm giving the only answer. Not to be a knowitall, but it helps with confidence when speaking if I can maintain that mindset.
