Am I the only one struggling with this type of social anxiety called Deipnophobia? And am I alone?

I been struggling with Deipnophobia since I was in 4th grade and I’m about to be in 9th and I really hate it but I do not know how to work on it or get rid of this social anxiety and am I the only one who struggles with this type of social anxiety and am I alone with this fear or is there other people who struggle with this social anxiety? And how can I work on it? and my friends are like why don’t you ever eat anything and I just lie and say something like I don’t know or I’m not hungry or just change the subject and they offer me food but I always deny it and even though I eat like everyone else I just can’t seem to get my mind to understand it is okay to eat in public or at school and I just fear people will judge me or say something mean and I always picture the worst case scenario like for example (eww why do you eat like that) or (no wonder why he never eats cuz he eats so ugly). and i also fear making like chewing noises when chewing in public and even though I eat normally I beat myself up and I always refuse to eat because of this anxiety and it keeps me from going to friends houses because I’m scared what if I have to eat something over there or you know, but I really want to get past this anxiety and just be able to eat in public and with friends like a normal human being should be able to. Am I alone with this anxiety and do other people have to go through this? Also (Deipnophobia is the fear of eating food with other people, especially the fear of eating in public or being judged while eating.)
