Victoria has a marked and persistent fear of people critiquing how she eats, so she consistently declines dinner invitations. which appears to be the most appropriate classification for victoria's problem?

Victoria's fear could be classified as a social phobia. This is my perception although I am not a physician. I found other classifications during my web searches such as Avoidant personality disorder (AvPD) described as a social anxiety. Another classification is Enosiophobia - fear of criticism.

Basically create a schedule on what you need to study and stick with it
