Having an audition next week but I keep getting "you lack confidence" feedback... Pls help😭

Hey guys, I have a big audition coming up next week and I’m losing my mind. Every time I get monitored or feedback from my trainers, they ALWAYS say the exact same thing: "You look so insecure" or "You lack confidence."

The thing is... I genuinely AM confident! In my head, I’m literally like 'I'm gonna crush this stage,' but I guess it’s just not translating to the outside? 😭 What am I doing wrong? Is it my eye contact, my posture, or what? If anyone knows how to actually look confident on camera when your inner vibe isn’t matching your outer vibe, please drop some tips. I’m desperate!!
