Physical appearance at work

I want to show up to work dressed professionally and with my hair and makeup done. However, I hate doing my hair and make up. I hate getting ready. I have immediate dread when I think about it. However, I am a surgical resident and my appearance reflects on my attendings so I feel the need to look nice for their clinic. Should I work on thoughts to motivate me to get ready? Should I work on thoughts that show me my worth is not based on how I look or what other people think of me?
C: Clinic in the morning
T: Ugh, I really don’t want to get ready for clinic
F: Dread
A: don’t get ready
R: I feel uncomfortable because I feel that I am not as presentable as I should be.
