I deal with this every convention I go to. It's hard to ignore them, it's even harder to not worry.
Best advice I can give is, fill your time with worth while people, find panels and events that spark your interest. Make plans to do dinner. And always remind yourself, you have as much privilege to be at that con as they do! If they talk behind your back, that's where it belongs! Behind you! If people believe them, why would you want ignorant people to even step in to your personal space.
