im going to a party and there will be a femboy :'c

one of my friends recently moved so he's having a party and he invited 2 groups of his friends which are the friend group im in with him and the other group being his work friends. apparently one of the people in the other group is a femboy and im so anxious and don't know what to do.. my friend group knows i like looking feminine and crossdressing but they got eyes too, they can tell i don't look like one of those hyper feminine femboys online.. now that they'll see what a feminine femboy looks like they'll all judge me and ill be the inferior person there.. i know ill see how good he looks and will be depressed all week and my bf will get tired of me acting up again and possibly leave me for the good looking femboy idk what to do..
