Hi, I have the exact same issue. I am scared of getting food in between my teeth, how I look when I eat…etc I’m so self conscious about it so I’m glad I’m not the only one. I would consider thinking about what was happening when this started to get worse for u, try to get down to the root issue of why you are so afraid of eating infront of others. Maybe practicing eating small snacks around other people, I also feel more comfy when others are eating with me or if there is background sound if u don’t like others hearing u chew. Watching tv and eating helps ease my anxiety when I’m with others as well. Find things you can do to slowly step out of your comfort zone and know u aren’t alone
