Sharing Our Innermost Thoughts

I’ve recently joined a new job after graduating recently. Joined as a photographer.
I feel very anxious here that I don’t even talk to people in office, I don’t eat lunch or anything the whole day because I feel anxious even doing that. I try to avoid work because I have performance anxiety and I feel like nobody will like my work or will find fault in my work and will then think how did I even manage to get this job in the first place. Although when I was shooting yesterday, everyone said they liked my work but for some shots if they find a mistake and they tell me I get anxious and something in my stomach. I sit on my phone and scroll Instagram or anything to avoid working to not feel anxious.
Am I the only one who feels this way? I’d love if somebody can give me some suggestions.
